html - CSS3 搜索框响应，搜索按钮分解

Question

我想为我的网站设计一个响应式搜索框，所以当我找到这个 codepen fiddle - http://codepen.io/nikhil/pen/GuAho ，我摆弄它并最终得到了这个版本 - http://codepen.io/anon/pen/Qygrpe

    /* CSS Search */

        .cf:before, .cf:after{
          content:"";
          display:table;
        }

        .cf:after{
          clear:both;
        }

        .cf{

<!-- language: lang-html -->

    <div id='search'>
        <div class='content-wrapper cf'>
          <form action='/search' id='searchform' method='get'>
    <input id='search-form' name='q' onblur='if(this.value==&apos;&apos;)this.value=this.defaultValue;' onfocus='if(this.value==this.defaultValue)this.value=&apos;&apos;' type='text' value='Looking for something?'/>
          <button class='search-button' title='Search' type='submit'><img alt='search button' src='http://4.bp.blogspot.com/-e8Tp2vSgy2c/VpS0vc8zi7I/AAAAAAAAAN0/6rDw0GIVaSg/s1600/mysearch2.png' title='Search'/>
    </button>
    </form>
    </div>
    </div>

我将搜索框的 HTML 代码及其 CSS 添加到我的博客模板中，在屏幕宽度超过 600 像素之前它都能很好地显示。看看

但是一旦宽度变为 600 像素或更小，我的搜索框就会分崩离析并且不会 float 在右侧，即使有足够的空间也是如此。我什至删除了菜单的几个部分，只留下“BLOGGER”和“MUSIC”，但搜索框仍然脱离了 div。

请指出我哪里出错了，我确定我在 CSS 的某个地方走错了方向。提前致谢。

尝试添加这个解决方案:

.content-wrapper {
    width: auto;
}
#search {
    position: absolute; // it was relative
}
div#menutop {
    position: relative;
}
