    <script>
        function showorhide(detail)
        {
            var p = document.getElementById("p");
            if(detail.open)
            {
                p.style.visibility = "hidden";
            }
            else
            {
                p.style.visibility = "visible";
            }
        }
    </script>
    <details id="detail" onclick="showorhide(this)">
        <summary>中国南海</summary>
        <p id="p"><mark>中国南海是神圣的.</mark></p>
    </details>
</body>
</html>

 效果图

代码如下:

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta charset="utf-8" />
</head>
<body>
    <script>
        function btn() {
            var i = 0;
            function thread() {
                if (i <= 100) {
                    i++;
                    updateprogress(i);
                }
            }
            setInterval(thread, 100);
        }
       
        function updateprogress(newvalue)
        {
            var progerss = document.getElementById("p")
            p.value = newvalue;
            p.getElementsByTagName("span")[0].textContent = newvalue;
        }
    </script>
    <section>
        <h2>progress元素的使用</h2>
        <p>完成的百分比<progress id="p" style="background-color:burlywood" max="100"><span>0</span>%</progress></p>
        <input type="button" onclick="btn()" value="dianji" />
    </section>
    <meter value="90" min="0" max="100" low="10" high="80"></meter>
    </br>
    </br>
    <input type="checkbox"  indeterminate id="checkboxtext" />
    <script>
        var check = document.getElementById("checkboxtext");
        check.indeterminate=true
    </script>
    </br>
    </br>
    <input type="image" src="4d33fe553927af2855ed237c93369706.jpg" alt="test" width="50" height="50"/>
</body>
</html>

其中indeterminate属性可以控制checkbox处于选中和非选中之间,在图中是一个横线,image主要展示了width和height属性,可以控制图片的宽度和高度.
