Replace the contents of header.php block for what I 'm going through. And put the css code in custom.css . Rename this file to header " header- p " . To avoid losing the customization of your block . Include the call .

Replace inside your template ( example - defaut - custom) the following line .
< ? php $ this - > loadBlock ( ' header' ) > by
< ? php $ this - > loadBlock ( ' header- p ) >

The css code for your custom css is this .


.span8logoimg {
margin-right:0px;
float:right;
}
.logo-image a {
background-repeat: no-repeat;
width: 204px;
height: 65px;
float: right;
}
.t3-logo {
float:right;
width: 182px;
height: 50px;
}

Delete all of your header.php block and put this :

defined('_JEXEC') or die;
$sitename = $this->params->get('sitename') ? $this->params->get('sitename') : JFactory::getConfig()->get('sitename');
$slogan = $this->params->get('slogan');
$logotype = $this->params->get('logotype', 'text');
$logoimage = $logotype == 'image' ? $this->params->get('logoimage', '') : '';
if ($logoimage) {
$logoimage = ' style="background-image:url('.JURI::base(true).'/'.$logoimage.');"';
}
?>

<!-- HEADER -->
<header id="t3-header" class="container t3-header">
<div class="row">



<?php if($this->countModules('head-search or languageswitcherload')): ?>
<div class="span4 clearfix">
<?php if ($this->countModules('head-search')) : ?>
<!-- HEAD SEARCH -->
<div class="head-search<?php $this->_c('head-search')?>">

</div>
<!-- //HEAD SEARCH -->
<?php endif ?>

<?php if ($this->countModules('languageswitcherload')) : ?>
<!-- LANGUAGE SWITCHER -->
<div class="languageswitcherload">
<jdoc:include type="modules" name="<?php $this->_p('languageswitcherload') ?>" style="raw" />
</div>
<!-- //LANGUAGE SWITCHER -->
<?php endif ?>
</div>
<?php endif ?>
</div>
<!-- LOGO -->
<div class="span8logoimg">
<div class="logo-<?php echo $logotype ?>">
<a href="<?php echo JURI::base(true) ?>" title="<?php echo strip_tags($sitename) ?>"<?php echo $logoimage ?>>
<span><?php echo $sitename ?></span>
</a>
<small class="site-slogan hidden-phone"><?php echo $slogan ?></small>
</div>
</div>
<!-- //LOGO -->


</header>
<!-- //HEADER -->
