html - 是否有可能在 css3 中完美地复制它？

Question

div: sidebar-top at http://alex.piechowski.org/school/ ...

CSS：

.sidebar-top {
float: left;
height: 32px;
width: 292px;
background: url(../images/sidebar_top.png) no-repeat;
padding: 4px 15px;
}

注意，是图片。没有那个图像可以吗？

Answer 1

您可以使用以下规则实现相当相似的效果：

border-top-right-radius: 12px;
border-top-left-radius: 12px;
border: 1px solid #ccc;
width: 290px;
background: -webkit-linear-gradient(top, white 0%,#ddd 100%);
background: linear-gradient(to bottom, white 0%,#ddd 100%);

Answer 2

我认为这个DEMO是你需要的

.sidebar-top {
background: #ccc;
border: 1px solid rgba(0,0,0,0.5);
border-radius: 6px;
-webkit-border-radius: 6px;
-moz-border-radius: 6px;
box-shadow: inset 0 -20px 40px #aaa, inset 0 20px 40px #fff, 0 2px 6px rgba(0,0,0,0.5);
-o-box-shadow: inset 0 -20px 40px #aaa, inset 0 20px 40px #fff, 0 2px 6px rgba(0,0,0,0.5);
-webkit-box-shadow: inset 0 -20px 40px #aaa, inset 0 20px 40px #fff, 0 2px 6px rgba(0,0,0,0.5);
-moz-box-shadow: inset 0 -20px 40px #aaa, inset 0 20px 40px #fff, 0 2px 6px rgba(0,0,0,0.5);
padding: 0px 20px 15px 10px;
width: 500px;
}

h2 {
text-align: center;
font-family: "Helvetica Neue", sans-serif;
color: #444;
text-shadow: 0 1px 1px #fff;
font-size: 14px;

是的，您可以使用下面提到的 css 从这里您可以生成基于 css 的渐变效果 http://www.colorzilla.com/gradient-editor/

.sidebar-top {
   background: rgb(254,255,255); /* Old browsers */
   /* IE9 SVG, needs conditional override of 'filter' to 'none' */

Answer 5

绝对地。

你需要设置 abackground-color然后你可以做 aborder来获得 1px 边框，它只 border-radius包含顶角，有点像这样：

background-color: grey;
border: 1px solid black;
border-radius: 5px 5px 0 0;

box-shadow要获得渐变，您可以使用设置 ainset来获得所需的渐变，或者按照另一个答案的建议，使用 a linear-gradient。
