Video code needed to make video wider

[NewOn]

Hello,

I need a code to make a video wider. I’m happy with the current height, but I want the video to stretch across the full width of the screen. Can anyone help? The code i'm currently using is:

<style>
video {
max-width: 60%;
height: auto;
display: block;
margin: 0 auto;
margin-left: 0px;
margin-right: 0px;
full-width: 100%;
}

</style>

Thanks so much in advance!
