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，这是一张图片。没有那张图片有可能吗？

Answer 1

您可以使用以下规则获得非常相似的效果：

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 DEMO 是您需要的

.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;
margin: -0 -20px 10px -10px;
padding: 5px 15px;
border-radius: 5px 5px 0 0;
-webkit-border-radius: 5px 5px 0 0;
-moz-border-radius: 5px 5px 0 0;
background: rgba(0,0,0,0.2);
border-bottom: 2px groove rgba(255,255,255,0.75);
box-shadow: inset 0 1px 1px rgba(255,255,255,0.5);
-o-box-shadow: inset 0 1px 1px rgba(255,255,255,0.5);
-webkit-box-shadow: inset 0 1px 1px rgba(255,255,255,0.5);
-moz-box-shadow: inset 0 1px 1px rgba(255,255,255,0.5);
}

Answer 3

绝对

你需要设置一个background-color，然后你可以border来获得1px边框，而border-radius只包含顶角，有点像这样：

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

要获得渐变，您可以使用box-shadow设置inset以获得所需的渐变，或者如另一个答案所示，使用linear-gradient。

Answer 5

是的，你可以使用下面提到的css 从这里你可以生成基于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' */
   background: url(data:image/svg+xml;base64,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);

   background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(254,255,255,1)), color-stop(35%,rgba(247,247,247,1)), color-stop(100%,rgba(238,238,238,1))); /* Chrome,Safari4+ */
   background: -webkit-linear-gradient(top,  rgba(254,255,255,1) 0%,rgba(247,247,247,1) 35%,rgba(238,238,238,1) 100%); /* Chrome10+,Safari5.1+ */
   background: -o-linear-gradient(top,  rgba(254,255,255,1) 0%,rgba(247,247,247,1) 35%,rgba(238,238,238,1) 100%); /* Opera 11.10+ */
   background: -ms-linear-gradient(top,  rgba(254,255,255,1) 0%,rgba(247,247,247,1) 35%,rgba(238,238,238,1) 100%); /* IE10+ */
   background: linear-gradient(to bottom,  rgba(254,255,255,1) 0%,rgba(247,247,247,1) 35%,rgba(238,238,238,1) 100%); /* W3C */
   border: 1px solid #d3d3d3;
   border-radius: 10px 10px 0 0;
   filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#feffff', endColorstr='#eeeeee',GradientType=0 ); /* IE6-8 */
   float: left;
   height: 32px;
   padding: 4px 15px;
   width: 292px;
}

是否有可能在css3中完美复制这个？
