1. Changing the Line Height Globally
Click once on any paragraph element to activate it. On the left sidebar make sure that the 'Make Changes To All Elements' button is ON. In this case, the line height is set to 2.
Select the 'Line Height' value that fits better your project.. For this example, we have Reduced the Line Height to 1.4.
2. Changing the Line Height For The Selected Object Only
If you only want to apply a line height change to a single element, click once on any paragraph element to activate it. Then on the left sidebar go to ensure that the 'Make Changes to All Elements' button is OFF. Then click on the 'Line Height' icon and select the value that fits better your project.
For this example, we have chosen the 'Double' setting for the paragraph in the middle.
*** As always, make sure that you apply the global changes before you start with the individual ones.
