Docking lets you attach an element to the sides of its container, be that the web page itself or another element like a box or tab. You can then create a margin between the sides and the element. No matter the size of the window or container the element will always be docked to the selected sides with the set margins.
1. Select the element you want to dock
2. Click on the desired dock button on the upper style toolbar:
In this example the text element is docked to the left and top of the box.
3. Drag the element in from the edge in order to choose the margin it will have from the borders (highlighted in grey)
