What is CSS?

CSS stands for Cascading Style Sheets. It is the language for describing the presentation of web pages, including colors, layout and fonts. It allows one to adapt the presentation to different types of devices, such as large screens, small screen, or printer.  

CSS allows you to store style presentation information (such like Layout and Colors) separate from your HTML structure which allows precision control of your Website layout and makes your pages faster and easier to update.

Custom CSS in WordPress?

Adding custom CSS to your own theme from Appearance Customize Screen in WordPress begins from WordPress version 4.7 without the need for child themes, theme editing.

Why Adding Custom CSS to your WordPress?

  • Using custom CSS can speed up development time.
  • Custom CSS ensures that whatever modifications you made on theme you’re using are preserved.
  • Custom CSS is loaded after the theme’s original CSS and thus allows overriding specific CSS statement, with you having to write the entire CSS set from scratch.
