Many WordPress users like to customize their sites and enhance the design of their themes by adding custom code. But many times, it can create problems if you add custom CSS code without the proper knowledge.

Nowadays, the WordPress themes typically come with the option to add custom code to change the default design. If your theme doesn't come with this default option to add custom CSS, you can use any of the following WordPress plugins.

Plus, it is always a good idea to keep dynamic changes in a WordPress plugin because if you add the code in the theme files, you can lose it during a theme update.
