What container are you trying to change?

When you made the change in firebug and it worked, were you changing the css properties on the right or adding inline styles?

I guess i don't understand by container... if it's a module, you can add a class suffix to it and match your LESS styles to that.

Hi philopin,

LESS variables are just a part of common values.

You have use Firebug to inspect, so you need to check for the right class and search for it instead.
As @Mainstwebguy's post, you should not add to inline-style.

Hello again Philopin,

Another option that may work for you is to create a custom css sheet and add your styling there. For example, if you are using the t3_blank template, you'll want to add your file here: <site root>/templates/t3_blank/css/custom.css

t3_will automatically recognize the new custom.css file and use the styles you have defined there. you can read more about doing this here.

Good Luck!

Hey sry i was a little busy....

okay thanks a lot for your anwsers.
The best answer was that i have to search for the classes!!!!!
I was always looking to find the stuff named in the rigth window of firebug
Now i have to search the classes in the less files and add e.g. background: @white;
It works i hope thats the right way to do it.

I also tried to edit it with the custom.css but i could not find it do i have to create my own new one because in the Documentation they say there should already be a custom.css. I was searching here templates/t3_blank/css

You need to know that I´m a beginner +german...
I also added a Picture of my design so you can see what i want to have...
maybe you have some useful tips for me.
For example i dont get the same spacing between my grids. For example I set position 1 to 3 in the Template menu.. but the margin is not the same...
I added a screenshot..

THANKS A LOT FOR YOUR HELP

Hi philopin,

For custom css, just take a look im that folder.
If you does not see it, just create a new one.

For Margin
You should check for GRID section on \templates\t3_blank\less\variables.less file.
You will find some glue there.

Regards
