1.默認播放按鍵不好看
2.設置自定義封面圖
以上這兩點都想自定義
1.使用div把video標簽蓋住
2.div中顯示自定義的海報圖片與按鈕
1.海報圖片作為div的背景
注:無論是橫圖還是豎圖,都希望按原比例顯示在div內
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
豎圖:
橫圖:
2.插入自定義播放圖標
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覆蓋到video標簽上
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.觸發播放方法
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();}
這樣就達到了之前的目的
總結:關鍵的還是 :background-position: center;
