element.style padding creating huge space between youtube videos

My youtube videos have huge space between them, when i checked the reason using ‘inspect element’ in google chrome, it shows the space is because of the following setting

element.style {
padding-top: 56.42857142857143%;
}

See link : http://www.riseleadershipgroup.com/wptest19_2/the-awakening-retreat/

How and where can i remove this so the padding is 0% and the space is gone from between the videos.

A quick repy will be much appreciated.
