7 useful code snippets for your Wordpress theme
Wordpress is an awesome CMS, and what makes it even more awesome is the ability to change the code without modifying the core, thanks to hooks and filters. You just need to use the right hook or filter and add it to your theme’s functions.php file. Here are 7 must-have functions in your functions.php file.

Add a noscript notice
Rarely, users might disable javascript in the browser or for a specific page. To remind them they’re viewing your site with disabled javascript you need to add a <noscript> tag to the <head> section:

If your theme doesn’t show descriptions for menu items, you can output them like this:
