@tuanphan how do i make the videos full screen on mobile. 

I want NO white space on the left and right like the screenshot:

There is a code that looks like this:

.blog-item-wrapper .sqs-layout>.row>.col>div:not(.image-block):not(.gallery-block):not(.embed-block) {
        padding-left: 9vw;
        padding-right: 9vw
}

You can override it by adding the block id of that image wrapper as selector:

@media (max-width: 480px) {
  #block-yui_3_17_2_1_1663999934171_4485 {
    padding-left:0;
    padding-right: 0
  }
}
