1.默认播放按键不好看
2.设置自定义封面图
以上这两点都想自定义
1.使用div把video标签盖住
2.div中显示自定义的海报图片与按钮
1.海报图片作为div的背景
注:无论是横图还是竖图,都希望按原比例显示在div内
css:
.yourDiv{ background-color: black; height:20em; background-image: url('./images/timg.jpg'); background-size: contain; background-repeat: no-repeat; background-position: center;}
html
<div class="yourDiv"></div>
效果
竖图:
横图:
2.插入自定义播放图标
css
.yourDiv { background-color: black; height:20em; background-image: url('./images/timg.jpg'); background-size: contain; background-repeat: no-repeat; background-position: center; display:flex; align-items: center;}.yourDiv img { width:20%; margin-left: 40%;}
html
<div class="yourDiv"> <img src="./images/play.png"></div>
效果
3.把div覆盖到video标签上
css
.yourDiv { background-color: black; height:20em; background-image: url('./images/timg.jpg'); background-size: contain; background-repeat: no-repeat; background-position: center; display:flex; align-items: center; position: absolute; top: 0px; left: 0px; width: 100%;}.yourDiv img { width:20%; margin-left: 40%;}.father { background-color: black; width:100%; height:16em; position: relative;}
htm5
<div class="father"> <video id="video" controls="controls" autoplay="autoplay" style="width:100%;height:16em"> <source src="./videos/v1.mp4" type="video/ogg" /> <source src="./videos/v1.mp4" type="video/mp4" /> </video> <div class="yourDiv"> <img src="./images/play.png"> </div> </div>
4.触发播放方法
html
<div class="father"> <video id="video" controls="controls" autoplay="autoplay" style="width:100%;height:16em"> <source src="./videos/v1.mp4" type="video/ogg" /> <source src="./videos/v1.mp4" type="video/mp4" /> </video> <div id="poster" class="yourDiv" onclick="play()"> <img src="./images/play.png"> </div> </div>
js
var video = document.getElementById("video");function play(){ document.getElementById("poster").style.display = "none"; video.play();}
这样就达到了之前的目的
总结:关键的还是 :background-position: center;
