使用此:
background: -moz-linear-gradient(315deg, transparent 10px, black 10px);
如何在不使用border
的情况下围绕它创建边框或轮廓?

这不是一个理想的解决方案,但我们可以使用颜色停止并使用::before
/ ::after
伪元素伪造边框,如下所示:
(由于简洁,省略了供应商前缀。)
div {
width: 150px;
height: 50px;
background: linear-gradient(315deg, transparent 10px, red 10px, red 12px, black 12px);
border-top: 2px solid red;
border-left: 2px solid red;
position: relative;
}
div::after, div::before {
content: "";
position: absolute;
background: red;
}
div::before {
width: 2px;
top: 0; right: 0; bottom: 14px;
}
div::after {
height: 2px;
left: 0; right: 14px; bottom: 0;
}
<div></div>

你可以使用盒子阴影,插入和/或开头,并根据你的意愿使用
div {
background:linear-gradient(45deg,yellow,purple,gray,lime,turquoise);
box-shadow:0 0 0 5px turquoise;
padding:2em 3em;
display:inline-block;
margin:0.5em;
}
div:nth-child(even) {
box-shadow:0 0 0 3px gray, 0 0 0 6px tomato,inset 0 0 0 2px ,inset 0 0 0 5px white;}
div:last-of-type {
box-shadow: 0 0;}
<div></div><div></div><div></div><div></div><div></div>
或继续使用渐变:
div {
background:
linear-gradient(to left, black, black) no-repeat,
linear-gradient(to top, black, black) no-repeat,
linear-gradient(to right, black, black) no-repeat,
linear-gradient(to bottom, black, black) no-repeat,
linear-gradient(to bottom left, gray,transparent,yellow) purple
;
background-position: left bottom ,right top , left top,left top ;
background-size: 100% 2px, 2px 100%,100% 2px, 2px 100%, 100%;
padding:2em 3em;
float:left;
margin:0.5em;
}
<div></div><div></div><div></div><div></div>
