前言

工作中，经常会用到一些分割线，这些分割线平时一般都用div来模拟，记得当时ie浏览器hr标签样式修改经常有问题。随着时代的进步，技术的发展。目前hr标签可以大胆的使用在工作中了，且可以自定义出各种样式，当然，今天的hr样式你也可以同样用div实现，不过hr分割线更加语义化一点点。

渐变的

代码：

.hr_gradient1 {

border: 0;

height: 1px;

background: #333;

background-image: linear-gradient(to right, #ccc, #333, #ccc);

}

.hr_gradient2{

border: 0;

height: 1px;

background-image: linear-gradient(to right, rgba(0, 0, 0, 0), rgba(0, 0, 0, 0.75), rgba(0, 0, 0, 0));

}

两边有修饰的

.hr-style-seven {

overflow: visible;

height: 30px;

border-style: solid;

border-color: black;

border-width: 1px 0 0 0;

border-radius: 20px;

}

.hr-style-seven::before {

display: block;

content: "";

height: 30px;

margin-top: -31px;

border-style: solid;

border-color: black;

border-width: 0 0 1px 0;

border-radius: 20px;

}

.hr-space-square {

border: 0;

color: #d0d0d5;

background: linear-gradient(currentColor, currentColor) no-repeat center;

background-size: calc(100% - 1.5em - 6px) 1px;

display: flex;

justify-content: space-between;

}

.hr-space-square::before,

.hr-space-square::after {

content: '';

display: block;

width: .75em; height: .75em;

transform: rotate(45deg);

box-sizing: border-box;

border: 1px solid;

margin: 3px;

}

复杂一点点的

.hr-double-arrow {

color: #d0d0d5;

border: double;

border-width: 3px 5px;

border-color: #d0d0d5 transparent;

height: 1px;

overflow: visible;

margin-left: 20px;

margin-right: 20px;

position: relative;

}

.hr-double-arrow:before,

.hr-double-arrow:after {

content: '';

position: absolute;

width: 5px; height: 5px;

border-width: 0 3px 3px 0;

border-style: double;

top: -3px;

background: radial-gradient(2px at 1px 1px, currentColor 2px, transparent 0) no-repeat;

}

.hr-double-arrow:before {

transform: rotate(-45deg);

left: -20px;

}

.hr-double-arrow:after {

transform: rotate(135deg);

right: -20px;

}

通用中间文字的

---

---

.hr-solid-content{

color: #a2a9b6;

border: 0;

font-size: 12px;

padding: 1em 0;

position: relative;

}

.hr-solid-content::before {

content: attr(data-content);

position: absolute;

padding: 0 1ch;

line-height: 1px;

border: solid #d0d0d5;

border-width: 0 99vw;

width: fit-content;

/* for IE浏览器 */

white-space: nowrap;

left: 50%;

transform: translateX(-50%);

}

文字带装饰

---

css代码同上，多了如下：

.hr-mid-border-content::after{

content: attr(data-content);

position: absolute;

padding: 4px 1ch;

top: 50%; left: 50%;

transform: translate(-50%, -50%);

color: transparent;

border: 1px solid #d0d0d5;

}

波浪

.hr-wavy {

border: 0;

color: #d0d0d5;

height: .5em;

white-space: nowrap;

letter-spacing: 100vw;

padding-top: .5em;

}

.hr-wavy::before {

content: "\2000\2000";

/* IE浏览器实线代替 */

text-decoration: overline;

/* 现代浏览器 */

text-decoration: overline wavy;

}

阴影

.hr-shadow {

border: 0;

padding-top: 10px;

color: #d0d0d5;

border-top: 1px solid rgba(0,0,0,.1);

box-shadow: inset 0 10px 10px -10px;

}

.hr-twill {

border: 0;

padding: 3px;

background: repeating-linear-gradient(135deg, #a2a9b6 0px, #a2a9b6 1px, transparent 1px, transparent 6px);

}

疏密可以控制的虚线

---

---

.hr-dashed-fixed {

border: 0;

padding-top: 1px;

/* for IE浏览器 */

background: repeating-linear-gradient(to right, #a2a9b6 0px, #a2a9b6 4px, transparent 0px, transparent 10px);

/* for 现代浏览器 */

background: repeating-linear-gradient(to right, #a2a9b6 0 var(--dashed-filled, 4px), transparent 0 calc(var(--dashed-filled, 4px) + var(--dashed-open, 6px)));//传入变量来定义疏密

}
