Clicking the Style tab in the top menu of the widget editor will bring us to even more customization options for the Before/After image slider.
In the Before/After Label tab, you can decide when you want the before and after labels to show. The dropdown lets you choose between Hover Only, Normal Only, and Hover & Normal.
For the example, I’ve picked Hover & Normal, which will show the labels at all times.
You can change the typography of the labels, font color and background color, and the padding of the text within the labels.
Under Alignment, you can set the labels to appear either at the top, in the center, or at the bottom.
