javascript - Fallback image for HTML5 video -

-

http://darrenbachan.com/playground/diamond-hand-car-wash/index.html

i'm trying set fallback image video banner. when site hits media query (mobile) i'd video become image, when refresh page i'm noticing class have giving dark grey background before video loads in. i'm thinking same image maybe present. want believe background-image set , when query hit maybe add display:none on video.

not sure if did correctly heres fiddle https://jsfiddle.net/8ucrarm0/

just in case that's terrible here's html/css:

html --> 

                    <div class="banner-text">                         <span class="logo-white"><img src="img/logo-white.svg" alt=""></span>                         <h1>feeling luxurious 1 car wash away.</h1>                         <h4>become diamond club member today.</h4>                             <button class="btn btn-primary btn-lg">see pricing</button>                     </div>                 </div><!-- end video-holder -->             </header>     </div><!--end banner-->

css:

#banner.container-fluid {     padding: 0;     position: relative; } #banner.overlay:after {     position: absolute;     content:" ";     top:0;     left:0;     width:100%;     height:100%;     display: block;     z-index:0;     background-color: rgba(0,0,0,0.8); } header {     position: relative;     overflow: hidden;     width:100vw;     height:100vh;     max-height:100vh;     text-align:center; } .banner-text {     position: relative;     top: 55%;     -webkit-transform: translatey(-50%);     -ms-transform: translatey(-50%);     -o-transform: translatey(-50%);     transform: translatey(-50%);     z-index: 1;     margin: 0 auto;     max-width: 550px;     /*left: 50%;*/     /*transform: translate(-50%, -50%);*/ } .banner-text h1, .banner-text h4 {     color: #fff; } .banner-text h1 {     padding-bottom: 20px; } .banner-text h4 {     padding-bottom: 40px; } .banner-text .logo-white {     width: 75px;     height: 65px;     display: block;     margin: 0 auto 20px auto; } .video-holder {     position:absolute;     height:100%;     width:200%;     left:-50%; } video {     position:absolute;     top: -99999px;     bottom: -99999px;     left: -99999px;     right: -99999px;     margin: auto;     min-height:100%;     min-width:50%; }

to fallback image html5 in mobile view.

you need use media queries.

css

@media screen , (max-width: 768px){   video{     display:none;   }     .full-img{     background: url('https://pbs.twimg.com/profile_images/686049493884665856/bw148x8r_400x400.jpg');     background-size: cover;   }
