Trying to wrap content div around thumbnail in WordPress Theme

I am building a WordPress theme and want to wrap the content of a single post around the thumbnail. I have tried floating the thumbnail div to the left and using float:none on the content div but it still doesn't wrap around the image.

.post-thumbnail{
    margin-right: 10px !important;
    margin-top: 10px;
    float: left !important;
}

.entry-content{
    float: none !important; 
}

Below is a page that I am tying to get to wrap around the thumbnail. I am using Elementor so I am not sure if that could be an issue. https://www.webstardesigns.co/building-a-social-media-platform-with-wordpress/
