初学css,怎么能获得这样的效果，调试了半天，都不行，请高人指点下！_html/css_WEB-ITnose
<!DOCTYPE html><html><head> <meta charset="UTF-8"> <title>Basic Tabs - jQuery EasyUI Demo</title> <style type="text/css">.divtop{ padding: 10px; background: black;}.divquery{ background: blue; height:200px; float:left;}.divbtn{ float:left; width:120px; background: red; height:200px;}.qitem { display:inline-block; line-height:30px; text-align:right; width:250px; height:25px; overflow:hidden; background: green;}</style></head><body> <div class="divtop"> <div class="divquery"> <span class="qitem"> </span> <span class="qitem"> </span> <span class="qitem"> </span> <span class="qitem"> </span> <span class="qitem"> </span> </div> <div class="divbtn"> </div> </div></body></html>我想实现的效果是，
1.红色的div和蓝色的div并列，当页面宽度变化的时候，红色的div的宽度固定，蓝色的div宽度自适应
2.绿色的div宽度固定，当宽度不够的时候，绿色的div能换行排列，现在这个没问题
现在的情况是，红色的div经常跑到蓝色下面去，如图:
请教如何调整？另外，黑色的div为什么只显示那么一点点?不是应该把蓝色和红色都覆盖吗？他是最顶层的div啊？
回复讨论(解决方案)
红色div float:right
红色div float:right
不行呢，换成right,还是在下面，只是变成靠右边了

谢谢！但是我不想定义divquery的宽度，因为我已经制定了divbtn的宽度，那么divquery的宽度就是剩余的部分了，如果指定宽度，或者用百分比，可能会导致页面有留白的部分,我希望他们能无缝的合并在一起呢
