無圖像的圓角問題

Question

有人可以向我解釋爲什麼底部的角落沒有擴大與div blockdark（高度：617px;）？ 角落只擴大至文本的結束的div內（container5）

這是CSS：

.container5 {background:#666666; color:#fff; margin:0 15px;} 

.rbottom{display:block; background:#f57f20;} 
.rtop{display:block; background:#eaeade;} 
.rtop *, .rbottom *{display: block; height: 1px; overflow: hidden; background:#666666;} 
.r1{margin: 0 5px} 
.r2{margin: 0 3px} 
.r3{margin: 0 2px} 
.r4{margin: 0 1px; height: 2px} 

.rl1 {margin: 0 0 0 5px; } 
.rl2 {margin: 0 0 0 3px; } 
.rl3 {margin: 0 0 0 2px; } 
.rl4 {margin: 0 0 0 1px; height: 2px;} 

.rr1 {margin: 0 5px 0 0; } 
.rr2 {margin: 0 3px 0 0; } 
.rr3 {margin: 0 2px 0 0; } 
.rr4 {margin: 0 1px 0 0; height: 2px;} 




div#blockdark { 
height: 617px; 
left: 468px; 
position: absolute; 
top: 150px; 
z-index: 1000000; 
width: 300px; 
overflow: visible; 
visibility: visible; 

} 

Thisi S中的HTML：

<div id="blockdark"> 
<!--Begin custome code--> 
<div class="container5"> 
<b class="rtop"><b class="r1"></b> <b class="r2"></b> <b class="r3"></b> <b class="r4"></b></b> 
<p>Sed do eiusmod tempor incididunt ullamco laboris nisi ut labore et dolore

veniam. In reprehenderit in voluptate mollit anim id est laborum. Duis aute 
irure dolor consectetur adipisicing elit, ut aliquip ex ea commodo consequat.</p> 

<p>Lorem ipsum dolor sit amet, qui officia deserunt cupidatat non proident. 
Eu fugiat nulla pariatur. Ut labore et dolore magna aliqua.</p> 
<b class="rbottom"><b class="r4"></b> <b class="r3"></b> <b class="r2"></b> <b class="r1"></b></b> 
</div> 
<!--End custome code--> 

</div>

因爲他們是在正常流量。

您需要將每個靠近元素底部的位置。

position: absolute; 
bottom: 0;
