前言

这里我整理一份我自用的工具类，我的用法并不是把所有的类存成一个css文件，而是项目中用到哪个，就拷贝哪个。

这些类的特点：不依赖于任何框架，也不需要任何说明文档。

常用

::-webkit-scrollbar {
  display: none;
}

.hidden {
  display: none;
}

.w-100 {
  width: 100%;
}

.h-100 {
  height: 100%;
}

.vw-100 {
    width: 100vw;
}

.vh-100 {
    height: 100vh;
}

浮动

.fl {
  float: left;
}

.fr {
  float: right;
}

.cb::after {
  clear: both;
}

position

.static {
  position: static;
}

.relative {
  position: absolute;
}

.absolute {
  position: absolute;
}

.fixed {
  position: fixed;
}

.position-0 {
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
}

.top-0 {
  top: 0;
}

.bottom-0 {
  bottom: 0;
}

.left-0 {
  left: 0;
}

.right-0 {
  right: 0;
}

flex弹性布局

.flex {
  display: flex;
}

.basis-xs {
  flex-basis: 20%;
}

.basis-sm {
  flex-basis: 40%;
}

  flex-basis: 50%;
}

}

  flex: 1;
}

  flex: 2;
}

}

  flex-direction: column;
}

  flex-wrap: wrap;
}

  align-items: flex-start;
}

.align-end {
  align-items: flex-end;
}

  align-items: center;
}

  align-items: stretch;
}

.self-start {
  align-self: flex-start;
}

  align-self: flex-center;
}

.self-end {
  align-self: flex-end;
}

.self-stretch {
  align-self: stretch;
}

.align-stretch {
  align-items: stretch;
}

.justify-start {
  justify-content: flex-start;
}

.justify-end {
  justify-content: flex-end;
}

.justify-center {
  justify-content: center;
}

.justify-between {
  justify-content: space-between;
}

.justify-around {
  justify-content: space-around;
}
