Edit a Rectangle Element
If you choose a text element in your layer list, two additional panels with settings will appear: Position and Element. You will find more information on the Position in our guide on How to position elements in your template.
At the moment, we offer one rectangle style: Choose the "Card" style to add a drop shadow to your element. (Stay tuned for more styles!)
There are two color fields, with which you can define the border and fill color for this element.
With the border radius setting, you can create rectangles with rounded edges or circles. Use the slider to change the radius of the edges.
You can also create circles with the border radius!
