Hi @dem10,
Am I right in assuming https://www.infoliga.schleider.com.ar is the site you’re trying to make those changes on? Are you trying to reposition the search box so that it’s in the upper most right corner of the site?
If so, firstly set up a child theme and then copy the parent theme’s header.php file to your child theme’s directory.
The following code in header.php defines the search box:
<div class="header-search">
<?php get_search_form(); ?>
</div>
You can reposition that code so it’s above your header and then target .header-search with some custom CSS to style it further.
Would you like to give that a try? We’ve gone through a few HTML and CSS changes together now and this is a good opportunity to put those skills to test. ??
Some good resources to help you out with this task are here:
