Hey there,
You can add the following CSS code into
Backend > EasyBlog > Themes > Custom CSS:
body #eb .eb-brand-name {
text-align:center;
}
As for to make the page heading to <h2>/<h3>, you can copy the
default.php file from
JoomlaFolder/components/com_easyblog/themes/wireframe/toolbar/default.php and paste it to template override location which is at
JoomlaFolder/templates/yourCurrentTemplate/html/com_easyblog/toolbar/default.php.
Then, look for the following PHP code from the
default.php file which is from the template override location:
<?php if ($view != 'entry' && !empty($title)) { ?>
<h1 class="eb-brand-name reset-heading"><?php echo JText::_($title);?></h1>
<?php } ?>
change the 'h1' to the heading that you want.
Can you have a try and see how it goes?
