The community member posted a question about how to make a responsive YouTube embed. Another community member provided a solution, suggesting to use a box > embed code approach, where the height and width of the embed code are set to 100% and the aspect ratio of the parent box is set to 16/9 (or any desired ratio). The original poster thanked the community member for the solution.
So that worked, but I was also able to set the aspect ratio on the embed element itself. Is there any reason to have a parent box? (For anyone else that reads this I set the embed code height and width to 100% but the styling on the embed element has the ratio and actual sizes)
