There are times when you want to reduce the width of a video, usually to stop your users from having to scroll on a desktop view. The best way to do this is to use a content block with a 3 column layout, put the video in the middle column and then adjust the percentage column widths:
1. First of all add a three column layout block and add your video to the middle column
2. Click on the outline of the content block to load the Layout Properties
3. Now adjust the Percentage Width of Column 2 (the middle column) to 70%. Columns 1 & 2 (the left and right columns) will automatically be set to 15%
4. Save and preview
Note: You can adjust the column percentage width to get exactly the sizing you need. This technique can also be used to adjust the size of other assets such as HotSpot Images.
