Using Child Themes
Child themes help customize WordPress safely. They protect your changes. First, make a new folder. Name it after your theme. Add “-child” to the name. Next, create a style.css file.

Custom CSS changes how your site looks. Use the style.css file. Write your CSS there. Want to change font size? Write font-size: 16px;. Need a new color? Add color: blue;. Save your changes. Look at your site. See the new style. Simple and easy!
