为什么有些时候<br/>标签连续用两次才能换行？

Question

<fieldset>

<legend> Your Details</legend>

    <label>Name<input type="text" name="Name"  /></label>

    </br>

    <label>Email<input type="text" name="Email"  /></label> 

</fieldset> 

<br/> 

<fieldset>

<legend> Your Details</legend>

    <br/>

    <label>How did you hear us?

    <select name="legen">

        <option value="Goole">Goole</option>

            <option value="Baidu">Baidu</option>

            <option value="Yoho">Yoho</option>

        </select>

    </label>

    <br/>错误在这里必须用两次<br/>才能实现换行

    <label>Would you visit again?

    <br/>

    <input type="radio" name="Yes" value="Yes">Yes

        <input type="radio" name="No"  value="No">No

        <input type="radio" name="Maybe"value="Maybe">Maybe

    </label>

</fieldset>
