Displaying a video as the background of your website is a sure-fire way to make a strong impact on your visitors. While animated, or video backgrounds aren’t suitable for all websites, if it’s a good match for the type of site you are building, and you execute it correctly, then they can really help create a memorable first impression on your target audience.
As video backgrounds are a web design trend that hasn’t yet reached saturation point, it’s an effect you can still make use of in order to stand out from the crowd and grab the attention of your visitors.
My advice here is to think carefully if video backgrounds actually add anything to your site. Will they increase user engagement? Will they enhance your visitors' experience of your site? If you can say yes to those questions, go for it.More WordPress Tips
