T3 Customization

Guidelines of how to customize T3 BS3 Blank template.

Template width is defined by grid, and divided into number of columns (default is 12 columns).

To change width of template, open file: variables.less in: templates/t3_blank/less then change defined width of template.

// Default 940px grid
// -------------------------
@T3gridWidth: 940px; // T3 add. For non-responsive layout.
@gridColumns: 12;
@gridGutterWidth: 40px;
@gridColumnWidth: floor((@T3gridWidth - @gridGutterWidth * (@gridColumns - 1)) / @gridColumns);
@gridRowWidth: (@gridColumns * @gridColumnWidth) + (@gridGutterWidth * (@gridColumns - 1));

We base on gridcolumn of 12. Width of each column is:

floor((@T3gridWidth - @gridGutterWidth * (@gridColumns - 1)) / @gridColumns); 

To change width of template, you just need to change T3gridWidth. The gridColumnWidth will be auto caculated.

From the base, we build up responsive grid system as follow:

// 1200px min
@T3gridWidth1200: 1200px; // T3 add
@gridGutterWidth1200: 40px;
@gridColumnWidth1200: floor((@T3gridWidth1200 - @gridGutterWidth1200 * (@gridColumns - 1)) / @gridColumns);
@gridRowWidth1200: (@gridColumns * @gridColumnWidth1200) + (@gridGutterWidth1200 * (@gridColumns - 1));

// 980px-1199px
@T3gridWidth980: 940px; // T3 add
@gridGutterWidth980: 40px;
@gridColumnWidth980: floor((@T3gridWidth980 - @gridGutterWidth980 * (@gridColumns - 1)) / @gridColumns);
@gridRowWidth980: (@gridColumns * @gridColumnWidth980) + (@gridGutterWidth980 * (@gridColumns - 1));

// T3 Add: 768px-979px
@T3gridWidth768: 740px; // T3 add
@gridGutterWidth768: 20px;
@gridColumnWidth768: floor((@T3gridWidth768 - @gridGutterWidth768 * (@gridColumns - 1)) / @gridColumns);
@gridRowWidth768: (@gridColumns * @gridColumnWidth768) + (@gridGutterWidth768 * (@gridColumns - 1));

All theme folders are located in: templates/t3_bs3_blank/less/themes/

In each theme folder, it has 3 files:

  • template.less this file includes style that is customized from default theme.
  • // Logo Text
    // ----------
    .logo-text h1 {
    color: @white;
    }
    
    // Taglines
    .logo-text .site-slogan {
    display: block;
    font-size: @font-size-base;
    margin-top: 5px;
    }
    
  • variables.less: this file includes customized variables from default variables.less file.
  • // Global values
    // --------------------------------------------------
    @t3-base-img-path:              "../../../images";
    @t3-theme-img-path:             "@{t3-base-img-path}/themes/dark";
    
    // Scaffolding
    // -------------------------
    @body-bg:                       @gray-darker;
    @text-color:                    @gray-lighter;
    
  • variables-custom.less: this file includes new variables that you create to customize current theme.
  • // Links
    // -------------------------
    @link-color:                    lighten(@blue, 20%);
    

Create new theme

The best way to create new theme is cloning theme folder.

You can do manual by creating new theme folder then add 3 files: template.less, variables.less and variables-custom.less

Customize Theme

In the back-end, you can select the new created theme for style you want then customize theme with ThemeMagic.

You can customize theme with LESS files of created theme in: templates/t3_bs3_blank/less/themes/dark-copy

Compile LESS to CSS

After customizing theme, please compile LESS to CSS. The new theme CSS files will be located in templates/t3_bs3_blank/css/themes/dark-copy

Please do not customize your theme with the CSS files, as they will overriden each time you run Compile LESS to CSS.

Added CSS files are:

  • bootstrap.css
  • home.css
  • megamenu.css
  • off-canvas.css
  • windows.css

All added css files will be loaded when site runs on the theme, by this way, all files are loaded from 1 folder only then it will improve site performance.

T3 Framework is developed with LESS, the LESS files are compiled to CSS files. Each time you compile, CSS files will be overridden so we suggest you not to use CSS to customize, develop your site because when you compile, your work can be lost.

The custom.css file is located in: templates/t3_blank/css . If you don't see the file, create new file then open that file to add CSS to style for your template.

Some characteristics of the custom.css file
  • The file is not included by default, you need to create new one.
  • The file is the last file to be loaded in your site.
  • The file is not a compiled file from LESS so it will not be overridden or lost when you compile.

Working with the file

The Custom.css file is the same as any other CSS file. Enter the CSS to style for your template.

.show-grid {
margin-top: 10px;
margin-bottom: 20px;
}
.show-grid [class*="span"] {
background-color: #eee;
text-align: center;
-webkit-border-radius: 3px;
-moz-border-radius: 3px;
border-radius: 3px;
min-height: 40px;
line-height: 40px;
}
.show-grid:hover [class*="span"] {
background: #ddd;
}

Let's check front-end

ThemeMagic

ThemeMagic is one of the outstanding feature in T3 framework. It helps you in customizing your JoomlArt T3 Framework version 3 based Joomla template without having to search for the right file or without diving into the code.

Still have trouble?

T3 Framework is powerful by its easy theme customization based on ThemeMagic. You are allowed to add unlimited parameters for customization.

You have to enable ThemeMagic first, then click on the ThemeMagic button to open ThemeMagic pannel.

Thememagic working pannel

  • Select theme to customize
  • Customize theme by changing parameter values
  • Click on preview to see the changes
  • Save or save as copy the customized theme

Add new parameters to ThemeMagic

You can add unlimited parameters, groups for theme customization. The customized parameters is set in the thememagic.xml file in the folder: templates/t3_bs3_blank

Note: Please note that the UPPERCASE texts are language keys

Step 1. Define a new group

<fieldset name="custom1_params" label="CUSTOM1_LABEL">
</fieldset>
<fieldset name="module_params" label="T3_TM_MODULE">
</fieldset>

Step 2. Define parameter in new group

<field name="@your-field-name"
type="type-of-parameter"
default="default-value-of-parameter"
label="FIEL_LABEL"
description="FIELD_DESCRIPTION" />
</field>
<fieldset name="module_params" label="T3_TM_MODULE">
<field name="t3-module-bg" type="color" class="t3tm-color" label="T3_TM_VARS_MODULE_BGCOLOR_LABEL" description="T3_TM_VARS_MODULE_BGCOLOR_DESC" />
</fieldset>

Step 3. Define LESS parameter

Define LESS parameter with the same name as defined above @your-field-name in file variables.less in template/less/.

// Module General
@t3-module-bg:                  transparent;

Step 4. Add "@your-field-name" somewhere in LESS file

It depends on you, just think how you want to use this parameter and how it affects to the template. It is required that you have some base knowledge about LESS and CSS. We suggest you to add to the file: style.less

.t3-module {
background: @t3-module-bg;
}

Step 5. Define language key

Open the language file of the template en-GB.tpl_t3_bs3_blank.ini located in language\en-GB\ and define language key that you use to define parameters above.

; MODULE
T3_TM_MODULE					="Module"
T3_TM_VARS_MODULE_BGCOLOR_LABEL			="Module Background Color"

Check in ThemeMagic to check whether new group and parameters are added or not

1. Change the Logo image

There are 2 ways to change the logo for a Joomla template developed with T3 Framework.

#1: Change logo from the Template Manager

Each style can go with different logo. To set style for the logo, please open Theme settings in Template style setting.

#2: Change the Logo from the variable.less file

Another way to change thelogo is changing the logo image path in variables.less file, which is located in the templates/t3_blank/less fodler.

// T3 LOGO
// --------------------------------------------------
@T3logoWidth:     60px;
@T3logoHeight:    50px;

@T3LogoImage:     "../images/logo.png";

You can also change the logo block size, by changing the value of the @T3logoWidth: and @T3logoHeight: variables.

2. Logo styling

To customize style for the logo, open the file style.less that is located in the templates/t3_blank/less folder. Search for the logo text, you'll find the style where you can either add more styles or customize it as is.

// Logo
// ---------------------------------------------------------
.logo {
float: left;

a {
display: inline-block;
line-height: 1;
margin: 0;
}

}

// Logo Image
// ----------
.logo-image {
overflow: hidden;

a {
background-image: url("@{T3LogoImage}");
background-repeat: no-repeat;
width: @T3logoWidth;
height: @T3logoHeight;
}

//hide sitename and slogan
span, small {
display: none;
}

}

Step 1: add the font package(s)

Upload your font package(s) to templates/t3_bs3_blank/fonts.

Step 2: define fonts

Now open file assets.xml located in the templates/template_folder/etc folder to define the font(s) you just added

<stylesheets>
<file>fonts/font-awesome/css/font-awesome.min.css</file>
<file>fonts/novecentowide/stylesheet.css</file>
</stylesheets>

Google Fonts

T3 Framework supports Google fonts, all you have to do is define the google font you would like to use in the assets.xml file (located in the templates/template_folder/etc folder).

<stylesheets>
<file>http://fonts.googleapis.com/css?family=Roboto+Slab:400,100,300</file>
</stylesheets>

To add new style sheets and Javascripts to T3 Framework, there are 2 ways to do that. You can either declare the new style sheets and Javascripts to head.php file or assets.xml file.

#1. Use head.php file

Open file head.php in the templates/t3_bs3_blank/tpls/blocks folder, then declare the new style sheets and Javascripts as you wish with the format as below.

Add CSS style sheets

<?php
// CUSTOM CSS
if(is_file(T3_TEMPLATE_PATH . '/css/custom.css')) {
$this->addStyleSheet(T3_TEMPLATE_URL.'/css/custom.css');
}
?>

Add Javascripts

<?php
if(is_file(T3_TEMPLATE_PATH . '/templates/TEMPLATE-FOLDER-NAME/js/slider/lofslidernews.mt11.js')) {
$this->addScript(T3_TEMPLATE_URL.'/templates/TEMPLATE-FOLDER-NAME/js/slider/lofslidernews.mt11.js');
}
?>

Just copy then correct the path to the CSS and Javascripts files.

Joomla provides addStyleSheet, addScript, addScriptDeclaration functions, which are the ones you should be using.

#2. Use assets.xml file

Another method to add new the CSS, Javascripts is embedding them to assets.xml, which is located in the templates/t3_bs3_blank/etc folder.

CSS style sheets and Fonts

Add the path to the style sheets and fonts you want to embed to your site. Use below format:

<stylesheets>
<file>fonts/novecentowide/stylesheet.css</file>
<file>http://fonts.googleapis.com/css?family=Roboto+Slab:400,100,300</file>
</stylesheets>

Javascripts

Add the path to the Javascripts files you want to embed to your site. Use the below format:

<scripts>
<file>js/jquery.mousewheel.js</file>
<file>js/iscroll.js</file>
<file>js/script.js</file>
</scripts>

1. Override 404 Page

Normally, each JA Template goes with its own 404 page style. If you would like to customize it, this will guide you through the quick how-to:

Step 1: add file error.php

The best way to add this file is to copy the default joomla error.php file in templates/system then copy to templates/t3_bs3_blank/

Step 2: Customize 404 page

Open this file and customize it as you want the page to be.

You can define which CSS file that the page will use.

<link rel="stylesheet" href="/<?php echo $this->baseurl ?>/templates/<?php echo $this->template ?>/css/error.css" type="text/css" />

You can create new css file for 404 page but we suggest to copy the default joomla error.css file in templates/system/css then paste to templates/t3_bs3_blank/css/ folder. Open the file and start your customization.

One more thing is that each theme can use different CSS file so that it will have different style.

<?php if($theme && is_file(T3_TEMPLATE_PATH . '/css/themes/' . $theme . '/error.css')):?>
<link rel="stylesheet" href="/<?php echo $this->baseurl ?>/templates/<?php echo $this->template ?>/css/themes/<?php echo $theme ?>/error.css" type="text/css" />
<?php endif; ?>

The css files of 404 page in each theme is located in templates/t3_bs3_blank/css/themes/theme_name/

Note:

The CSS files are NOT overridden when you compile LESS to CSS.

2. Override offline page

To customize the Offline Page, you only need to go through the same procedure as you do for the 404 page customization

Step 1: add new offline.php file.

Copy the file offline.php in folder templates/system then paste to templates/t3_bs3_blank

Step 2: Customize Offline page

Open this file and customize it as you want the Offline page to be.

You can define which CSS file that the page will use.

<link rel="stylesheet" href="/<?php echo $this->baseurl ?>/templates/<?php echo $this->template ?>/css/offline.css" type="text/css" />

You can create new css file for Offline page but we suggest to copy the default joomla offline.css file in templates/system/css then paste to templates/t3_bs3_blank/css/ folder.

You can define each theme to use a css file so that each theme will have different style for Offline page.

<?php if($theme && is_file(T3_TEMPLATE_PATH . '/css/themes/' . $theme . '/offline.css')):?>
<link rel="stylesheet" href="/<?php echo $this->baseurl ?>/templates/<?php echo $this->template ?>/css/themes/<?php echo $theme ?>/offline.css" type="text/css" />
<?php endif; ?>

The css files of Offline page in each theme is located in templates/t3_bs3_blank/css/themes/theme_name/

Note:

The CSS files are NOT overridden when you compile LESS to CSS.

The "Back to top" button allows you to quickly navigate to the top of your site.

Step 1: enable "back to Top" button

To add this button in your site, open the file footer.php located in the templates/t3_bs3_blank/tpls/blocks/ folder

Add the following code to the file.

<!-- BACK TO TOP -->
<div id="back-to-top" class="back-to-top">
<i class="icon-angle-up"></i>
</div>
<script type="text/javascript">
//<![CDATA[
(function($){
$(document).ready(function(){
// back to top
(function(){
$('#back-to-top').on('click', function(){
$('html, body').stop(true).animate({
scrollTop: 0
}, {
duration: 800,
easing: 'easeInOutCubic',
complete: window.reflow
});

return false;
});
})();
});
})(jQuery);
//]]>
</script>
<!-- //BACK TO TOP -->

Step 2: add js file

Download the jQuery Easing Plugin then copy the file jquery.easing.1.3.js

Download jQuery

Now paste that jquery.easing.1.3.js file to folder templates/t3_bs3_blank/js.

Next, embed the new JS file by defining the file in the assets.xml file in templates/t3_bs3_blank/etc.

<scripts>
<file>js/jquery.ellipsis.js</file>
</scripts>

Step 3: style "back to Top" button

Now add style for the button, using any LESS file in the templates/t3_bs3_blank/less/ folder .

We suggest to add style to file style.less

// BACK TO TOP
// ---------------------------------------------------------
.back-to-top {
background-color: @T3primaryColor;
bottom: 15px;
height: 40px;
margin: 0;
position: fixed;
right: 15px;
width: 40px;
z-index: 1000;
.opacity(0);
.transition(opacity 350ms);

&.reveal {
.opacity(30);
cursor: pointer;
&:hover, &:focus, &:active {
.opacity(100);
}
}

i {
color: @white;
font-size: 12px;
line-height: 1em;
left: 50%;
margin-top: -7px;
margin-left: -3px;
position: absolute;
top: 50%;
}
}

T3 Framework supports Megamenu, when you run a multilingual site, you have to configure multi-language for Megamenu. Follow this guide to make it work.

Please make sure all the steps in setting up a multilingual site are done completely. If these steps weren't not done yet, there are 2 ways to build up a multilingual site: manual setup or auto setup with JA Multilingual Component. It's up to you to go either way.

Manual Setup Guide JA Multilingual Guide

Create menus for languages

Step 1: Create menus for languages

For each language, you will need to create a menu system based on the default language menu system. For example, your site is curently in 2 languages: English and Arabic. Then you should create menus for Arabic language based on the existing menus of theEnglish language.

In fact you don't need to translate all the menus, you just need to translate all the menus that are being used.

Step 2: Duplicate the default template style

Go to Extensions >> Template Manager then duplicate the default template style.

Step 3: Rename and assign language for the duplicated template style

Next, open the duplicated template style to rename it. Then assign to the desired language.

Step 4: Assign menu for Megamenu

Now open the Navigation tab, enable Megamenu then assign the created menu in the Menu field.

Step 5: Save Mengamenu settings

Now all you have to do is SAVE the Megamenu settings, please keep in mind that this step is required even if you haven't change anything as it aims to detect your Megamenu.

Open the Megamenu setting panel and then make sure you select the right menu - Mainmenu for Arabic language.

T3 Framework allows you to create multiple instances for Megamenu. In this writing, we will create Megamenu for Main Menu and Top Menu on a site.

Step 1: create mainmenu and topmenu

Step 2: create menu items for mainmenu and topmenu

Step 3: create topnav.php file

Duplicate file mainnav.php in templates/t3_bs3_blank/tpls/blocks then rename to topnav.php.

Step 4: customize mainnav.php file

Open mainnav.php file then change:

Find the code

data-target=".t3-navbar-collapse"

Replace with:

data-target=".t3-navbar-mainmenu"

"mainmenu" is the menu type name of Main Menu.

Add class t3-navbar-mainmenu

Find the code

<div class="t3-navbar-collapse navbar-collapse collapse"></div>

Replace with:

<div class="t3-navbar-mainmenu t3-navbar-collapse navbar-collapse collapse"></div>

Step 5: customize topnav.php file

Open topnav.php file then replace the following code.

Find the code

data-target=".t3-navbar-collapse"

Replace with:

data-target=".t3-navbar-topmenu"

Add class t3-navbar-topmenu

Find the code

<div class="t3-navbar-collapse navbar-collapse collapse"></div>

Replace with:

<div class="t3-navbar-topmenu t3-navbar-collapse navbar-collapse collapse"></div>

Find the code

<jdoc:include type="<?php echo $this->getParam('navigation_type', 'megamenu') ?>" name="<?php echo $this->getParam('mm_type', 'mainmenu') ?>" />

Replace with:

<jdoc:include type="<?php echo $this->getParam('navigation_type', 'megamenu') ?>" name="'topmenu" menutype="topmenu" />

Please note that the topmenu is from menu type name.

Step 6: call loadBlock for topmenu

Open file home-1.php or default.php in templates/t3_bs3_blank/tpls.

<?php $this->loadBlock ('topnav') ?>
