(this is a video of my feet, don't laugh, it has gotten 1,645 views)
What can I do about this to fix the problem you ask. There are a couple of options.
One you can go to the video source. Mine is from YouTube. YouTube has this really cool feature, that allows you to re-size, and add a color boarder to it. All you do is to click on the embed code and a window shows up for you to make your changes. Its really simple.
The second way is to change the code. All you do is change the width numbers in the code.
You will have to change both numbers, and they both have to be the same numbers. If you make a mistake, it will not work.
Have a great day,
