How to Add two Buttons the Divi Fullwidth Slider

For now it isn’t easy to add a second button on the fullwidth slider, but I expect Elegant Themes will eventually add it as a feature. Below I’ll provide a couple examples of how you can get it done.

  1. Add a Fullwidth slider module and create new slide.
  2. Make sure you are on the text editor mode for the slide
  3. Add your own variants code and don’t forget to save
  • Do not flip back and forth between text and visual editor or it will remove the formatting…

With Child Theme: (Looks Better on Phones)
Insert the following code into the content area of the slide.

Button 1 Text            Button 2 Text
Add this to your child theme…

/*————————————————*/
/*—————[Button Example]—————–*/
/*————————————————*/
@media (max-width: 767px) {
.phoneFixExample {
display: block;
min-width: 225px;
margin-left: auto;
margin-right: auto;
margin-top: 5px;
margin-bottom: 5px;
}
.hideStuff {
display:none;
}
}

No Child Theme Version – Slide 2
Insert the following code into the content area of the slide.

Button Text            Button 2 Text
One method to reduce the height of the full width slider.
If you are trying to figure out how I made the slider above narrower… Go to the Advanced tab and add a variation of the following to “slide description”.

position: relative;
top: 30px;
padding-top: 0;
padding-bottom: 0;
min-height: 225px;
