CSS实现对角边框样式
CSS实现对角框,边角加个边框、四角框
一:线性渐变方式:
鼠标悬停触发显示:hover {
background: linear-gradient(to left, #043add, #043add) left top no-repeat,
linear-gradient(to bottom, #043add, #043add) left top no-repeat,
linear-gradient(to left, #043add, #043add) right bottom no-repeat,
linear-gradient(to left, #043add, #043add) right bottom no-repeat;
/*设置大小*/
background-size: 0.12rem 1rem, 1rem 0.12rem;
}二:伪类
默认是透明opacity: 0; 鼠标悬停触发显示增加css3过渡效果,显示更平滑
:before {
position: absolute;
bottom: 0;
left: 0;
width: 20px;
height: 20px;
content: "";
border-left: 2px solid #043add;
border-bottom: 2px solid #043add;
transition: all 0.6s ease;
opacity: 0;
}
:after {
position: absolute;
top: 0;
right: 0;
width: 20px;
height: 20px;
content: "";
border-right: 2px solid #043add;
border-top: 2px solid #043add;
transition: all 0.6s ease;
opacity: 0;
}
:hover:before,
:hover:after {
opacity: 1;
}左下——右上对角边框,也可以左上——右下对角、四个角。
自己增改代码。
不懂可以留言!
