How I can make change color of text or background of section div by entry user color ?

Answer 1

Using Javascript

First, you need to get a reference to the element whose color is to be changed.

You can use document.querySelector() if there is only one element.

Or use document.querySelectorAll() if there were many elements to work with.

Accept input for the color value in decimal or hexadecimal format, validate the input, and assign the value as fore color or background color of the element(s).
