To add a color overlay to the background image, I am going to use CSS.
First of all, adding a background image color overlay is the most dynamic way of creating tinted web page images. It became popular to many websites which appear in homepage as banners.
The great thing about adding background image color overlay is that you can just change any image (normal image without filter) dynamically and publish it on your website with filter, thanks to CSS.
So, how to do it?
