Hello,

I saw the screenshot you attached. To add highlight the text as in the screenshots you need to add the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.

To add background color use the following CSS.

.woodmart-prefooter h4 span {
background: yellow;
}

To change only the color of text use the following CSS.

.woodmart-prefooter h4 span {
color: red;
}

You can set the color accordingly.

Best Regards.
