set image above text in fullwidth slider

I don't think there is such an option to set. You can set the background image and then center the text on the slide.

 

I suppose you can do it like this.

Go to your media library and copy URL of that logo you want to put above text in the fullwidth slider.


Then go to the content of the slide you want to change, click on the text and add this.


You need to delete title otherwise it will appear above the image. If you want it, you can put h3 tab bellow the image code in the text area.
<img width="ADJUST_THE_PROCENTILE" src="URL_OF_THE_LOGO">

Hope this helps. Maybe there are better ways but this is a hack from the top of my head. Never seen anybody had the need for image to be on top of text on the slider in divi.

 

You just give your h1 a class like this. <h1 class="awesome-heading">My Title</h1>

Than write media queries.
/*DESKTOP*/
.awesome-heading {
font-size: 40px;
}

/*TABLET*/
@media (max-with: 980px) {
.awesome-heading {
font-size: 30px;
}
}

/*SMALLER TABLETS AND PHONES*/
@media (max-with: 767px) {
.awesome-heading {
font-size: 20px;
}
}
