For WordPress Full Site Editing (FSE) users:
<ul>
<li>FSE reduces the need to access and edit core theme files, which can make it harder for advanced users who prefer working directly with PHP or CSS in template files.</li>
<li>Some modifications may require custom block creation, which involves more advanced coding.</li>
<li>Since <a href="https://wpbrandy.com/full-site-editing-in-wordpress/" rel="nofollow ugc">FSE themes</a> are heavily block-based, any manual modifications to theme files might be overridden during updates, so adding code snippets needs to be done carefully.</li>
<li>When adding PHP or backend functionality, rely on plugins like Header Footer Custom Code to avoid directly editing theme files.</li>
</ul>
<h4>INSTALLATION</h4>
Manual installation is easy and takes fewer than one minute.
