我试图用页眉和页脚来创造圆角。 我能够强迫页眉在上面,但我不明白为什么我不能强迫脚脚脚在下面。
事实上, 位置绝对; 底部: 0; 但这只是我的脚在文本的宽度。 当我添加宽度: 100%; 时, 页脚会变大吗??

您设定了 left: 0
和 right: 0
, 不是 width: 100%;
- 见测试 http://jsfiddle.net/thebabydino/GN9q5/3/

确实您在此拥有绝对位置, 且 < code> width 和 < code> width : 自动 < /code > 将无法这样做, 但您必须明白, < code> width: 100 {/ code> 意指容器的 < em> width < strong >, 没有 strong > 粘贴和边框 em > (除非您使用 < code > box- sizing: 边框 code > ) 。
您在 px 中指定了 div s 宽度, 所以您可以在 px 中指定页脚宽度吗? 例如 : < a href="http://jsfiddle. net/ GN9q5/4/" rel= “ no follow” > http://jsfiddle. net/ GN9q5/4/
只有改变这个 cs 和它是要去工作; -)
.rcs .ftr {
margin:110px 0 0 0;
font-size:1.2em;
padding:5px 0px 5px 10px;
border-bottom-left-radius: 0.35em;
border-bottom-right-radius: 0.35em;
border-top:1px solid #AAAAAA;
}
见“http://jsfiddle.net/GN9q5/5' rel=“no follow'>http://jsfiddle.net/GN9q5/5
绝对定位元素已不再是布局的一部分。 它们不知道父元素有多大, 所以您必须将宽度设置为静态值 。
您必须用绝对值设置您的 width
, 并计算折叠。
示例:
If you have a width of 960px and a padding of "5px", your with must be 950px.
You SHOULD remove it for reason that I don t exactly know.
/*footer*/
.rcs .ftr {
margin:0;
font-size:1.2em;
padding:5px 5px 5px 10px;
position: absolute;
bottom: 0px;
width: 385px;
border-bottom-left-radius: 0.35em;
border-bottom-right-radius: 0.35em;
border-top:1px solid #AAAAAA;
}
您的容器宽度设置为 400px. 左键 & amp; 右键嵌入 = 15px, 减去后将宽度设为 385px 。
