Block Editor: Use the Custom HTML block to add snippets like tables, iframe embeds, or custom containers directly into your pages.
Theme Files: For structural changes (like adding a site-wide banner), you would edit header.php or footer.php in your Astra theme (ideally using a child theme to prevent losing changes during updates).
**2. Managing Scripts (JavaScript)**
Standard Method: Use wp_enqueue_script() in your functions.php file. This prevents the same script from loading multiple times, which can break site functionality.
Header/Footer Scripts: If you need to add tracking codes (like Google Analytics or Meta Pixel), you can use a plugin or the built-in options in your Hostinger tools to safely inject code into the <head> or <footer>.
**3. Performance & Optimization**
LiteSpeed Cache: Since you have LiteSpeed Cache active, you can use its “Page Optimization” settings to Minify and Combine your HTML and JS files. This reduces the number of requests and file sizes, making your site load faster.
Defer/Async: You can set non-essential scripts to load “Defer” or “Async” so they don’t block the visual rendering of your page.
**4. Security Warning**
Script Injection: Be cautious when pasting scripts from the web. Malicious scripts can steal user data or give attackers access to your site. Always verify the source.
