Why we use external CSS file?

Question

Why we use external css file (.css)

Answer 1

External stylesheets allow you to completely separate your CSS from your HTML.

The benefits of using an external style sheet are:

-Everything is stored within a single file.

-Once changed/updated, the changes are reflected on all other pages that reference the stylesheet.

-This makes it easier to maintain larger websites.

-Pages load quicker once the main CSS file has been cached, As a result bandwidth goes down.

-Effectively, you’re able to change the entire look and feel of a website through a single file.
