Hi..
Suppose there are 10 CSS in the coding of a webpage. Now 5 of them have many unused selectors. How does this affect my webpage? Will it decrease performance? Will it impact security? What is the impact of keeping unused selectors within CSS on a page?

Marginal if any affect. If anything the page would have a practically undetectable longer load time - as the size of the style sheet would be slightly larger. The biggest advantage to keeping your stylesheets optimized is for convenience when editing them or troubleshooting.

hello everyone….....newbie here…......

You will not see any noticeable delay. The only issue would be tracking down the correct CSS style that is being displayed.

Not an issue but you may have CSS conflicts.
