For some reason I can never find the correct location to remove the blue link text from Elegant themes Divi or Divi builder buttons.
I sort of think it might be a bug they will get fixed because it doesn’t show up in preview. In your child theme, add the following bit of code and change the color to whatever you flat color or hex value you want.
/*—[Taking out blue link text on Divi buttons]–*/
If you don’t have a child theme for Divi and would like to make one go here. https://divi.space/divi-child-theme-builder/
Make sure you select your child theme as your active theme–> Go to appearance–> Editor
It should look something like this.
You shouldn’t need to use !important as long as you use the correct selector.
