Use 1 text widget as its title and display none the real title.
So we have this pattern.
- [A] = text widget without title, and with image in its content functioning as title for the following widget.
- [B] = any widget that has [A] as a title.
In your site right now, drag 1 text widget and place it above the categories widget. In that text widget, put this in.
<img class="aligncenter" src="https://www.dianna.dk/category-title.jpg" alt="Category Title">
Notice the aligncenter
class, it’s helpful for small screen. You need this class because your image is small, it needs to align center to look good in small screen. But if you use a bigger image like 600×80, you might not need this class.
In CSS put this in to hide the real title and adjust some margin.
#categories-2 .widget-title {
margin-bottom: -48px;
text-indent: -9999px;
}
Edit: I just saw there is Custom CSS code in <head>
, so you already have Custom CSS plugin.
