如果在此代码基础上
可以这样
<form>你对什么运动感兴趣:<br />
<label for="run">慢跑</label>
<input type="checkbox" name="gender" id="run" />
<br />
<label for="climb">登山</label>
<input type="checkbox" name="gender" id="climb" />
<br />
<label for="basketball">篮球</label>
<input type="checkbox" name="gender" id="basketball" >
</form>
就是普通标题<hx></hx>吧
<caption>标题文本</caption>
<caption>This is a caption</caption>
