html - 带角度的带 css 图像
问题描述
我正在尝试在图像上创建一个有角度的角带。如以下屏幕截图所示，我想在已售出的商品上显示“已售出”功能区
下面是我使用 bootstrap 4 显示项目的 codepen 的链接。到目前为止，我能够显示 SOLD 功能区，但不知何故，它出现在屏幕顶部，而不是图像/项目。如果有人指导我在售出的物品上显示 SOLD 丝带，那将是非常有帮助的。据您所知，我在 CSS 方面的经验很少。
代码笔： https ://codepen.io/stephen0roper/pen/pQbjbq
这是我为显示功能区创建的示例代码：
/* The ribbons */
.corner-ribbon {
font-weight: bold;
width: 200px;
background: #e43;
position: absolute;
top: 25px;
left: -50px;
text-align: center;
line-height: 100px;
letter-spacing: 1px;
color: #f0f0f0;
transform: rotate(-45deg);
-webkit-transform: rotate(-45deg);
}
/* Custom styles */
.corner-ribbon.sticky {
position: fixed;
}
.corner-ribbon.shadow {
box-shadow: 0 0 3px rgba(0, 0, 0, .3);
}
/* Different positions */
.corner-ribbon.top-left {
top: -10px;
left: -103px;
transform: rotate(-45deg);
-webkit-transform: rotate(-45deg);
background-color: red;
width: 256px;
height: 75px;
}解决方案
因为您使用position: fixed;而不是 absolute for .corner-ribbon。您还需要overflow: hidden;.card 类。这是工作示例：
/* The ribbons */
.corner-ribbon{
font-weight: bold;
width: 200px;
background: #e43;
position: absolute;
top: 25px;
left: -50px;
text-align: center;
line-height: 100px;
letter-spacing: 1px;
color: #f0f0f0;
transform: rotate(-45deg);
-webkit-transform: rotate(-45deg);
}
.card {
overflow: hidden;
}
.corner-ribbon.shadow{
box-shadow: 0 0 3px rgba(0,0,0,.3);
}
/* Different positions */
.corner-ribbon.top-left{
top: -10px;
left: -103px;
transform: rotate(-45deg);
-webkit-transform: rotate(-45deg);
background-color: red;
width: 256px;
height: 75px;
