CSS background-color Property
CSS background-color property sets an element background color. The background of an element is the total size of it which includes padding and border (but not the margin).
So, for setting a background color you need to choose any color. You can choose colors from our Color Picker tool. The color can be written like the following types: a color name - “red”, a HEX value - “#ff0000” and an RGB value - “rgb(255,0,0)”.
It is important to ensure that the contrast ratio between the background color and the color of the text placed over it is high enough, so people with low vision will be able to read the content of the page.
