Today I looked at the div+css implementation of Think’s rounded rectangle. This is roughly what he did.
It accumulates or decreases bit by bit according to the margin. The results are relatively good! Just practice and study~
html part
<!-- round main --> <div id="round"> <!-- r_top ---> <div class="r_top"> <em class="r_a"></em> <em class="r_b"></em> <em class="r_c"></em> <em class="r_d"></em> </div> <!-- //r_top end ---> <!-- r_box ---> <div class="r_box"> 这是一个圆角矩形!<br /> 这是一个圆角矩形!<br /> 这是一个圆角矩形!<br /> 这是一个圆角矩形!<br /> 这是一个圆角矩形!<br /> 这是一个圆角矩形!<br /> </div> <!-- //r_box end ---> <!-- r_bottom ---> <div class="r_bottom"> <em class="r_d"></em> <em class="r_c"></em> <em class="r_b"></em> <em class="r_a"></em> </div> <!-- //r_bottom end---> </div> <!-- // round main end-->
css part
div,em{ margin:0; padding:0;} #round{ width:500px; margin:0px 20px; } .r_top,.r_bottom{ display:block; font-size:1px;} .r_a,.r_b,.r_c,.r_d{ display:block; overflow:hidden; } .r_a,.r_b,.r_c{ height:1px;} .r_b,.r_c,.r_d{background:#CCFF66; } .r_box{ background:#CCFF66; padding-left:10px; padding-right:10px;} .r_a{ margin:0 5px; } .r_b{ margin:0 3px; border-width:0 2px; } .r_c{ margin:0 2px; } .r_d{ height:2px; margin:0 1px; }
Test compatibility. It's ok for now. I haven't found any major problems yet~~.
为了更好的理解,先用简单的代码为例。XHTML代码:<b class="top"><b class="b1"></b><b class="b2"></b><b class="b3"></b><b class="b4"></b></b>CSS代码:b{display:block;}.b1,.b2,.b3,.b4{overflow:hidden;height:1px;border-left:1px solid #000;border-right:1px solid #000;}.b1{margin:0 5px;background:#000;}.b2{margin:0 3px;border-width:0 2px;}.b3{margin:0 2px;}.b4{height:2px;margin:0 1px;}
