The line-layering technique uses no images and no javascript, only display: block bold tags layered on top of each other. We simply create lines with decreasing side margins, stick them on top of each other and we have a well-emulated round corner.
.b1f, .b2f, .b3f, .b4f{font-size:1px; overflow:hidden; display:block;}
.b1f {height:1px; background:#ddd; margin:0 5px;}
.b2f {height:1px; background:#ddd; margin:0 3px;}
.b3f {height:1px; background:#ddd; margin:0 2px;}
.b4f {height:2px; background:#ddd; margin:0 1px;}
.contentf {background: #ddd;}
.contentf div {margin-left: 5px;}
<b class="b1f"></b><b class="b2f"></b><b class="b3f"></b><b class="b4f"></b>
<div class="contentf">
<div>Round FILL!!</div>
</div>
<b class="b4f"></b><b class="b3f"></b><b class="b2f"></b><b class="b1f"></b>
Din cauza framework-ului wordpress se injecteaza tag-urile HTML in editor, de acea nu pot sa afisez corect exemple, le puteti vedea [ aici ]
