css - 不需要的垂直滚动条

Question

即使内容没有占据整个页面，我在所有浏览器中都有不需要的垂直滚动条。欢迎改进和更改 css!

 <div id="header">
 </div>
 <div id="container">
     <div id="title"><h2>Admin</h2></div>
     <div id="content">
         <div class="login">
             <div>&nbsp</div>
                 <form method="post" action="/admin/index.php">
                  <p><input type="text" name="username" value="" placeholder="Username"></p>
                  <p><input type="password" name="password" value="" placeholder="Password"></p>
                  <p><input type="submit" name="login" class="button" value="Send"></p>
                  <p class="error">&nbsp;</p>
                 </form>
            </div>
        </div>
    </div>
<div id="footer">
    <p>Copyright &copy; 2010-2013</p>
</div>

Answer 1

从您的 CSS 元素中取出最小高度。这是一个 example .以下是您想对 CSS 代码执行的操作:

     #container {
        margin-left:auto;
        margin-right:auto;
        width:70%;
      }

这应该可以解决垂直滚动条的任何问题。
