When editing a text element in Bannerwise you can decide if you want to scale the contents to fit the placeholder.
When you are editing an ad set in the All view, you simply select a text element and the properties of that text element will show like you're used to. Under the Text option , you will find the toggle that allows you to stretch the contents of the text.
Similarly, you will find this toggle in the Single view when you're editing a specific ad size.
In the Single view, it is placed below the "Text" option which shows if you click a text element. Here, the interaction works the same as in the All view.
Using this functionality can help you style text elements in your ads with ease.
