编程打卡：给网页做个花里胡哨个格子纹理背景吧。

嗯

看到Github上面有一个项目，格裙纹理生成器稍微玩了一会儿，感觉这样的纹理或许可以用来做网页的背景，就这样做了。

这个项目生成的图片，感觉太精细了，，稍微一个SVG，就有好几MB大，虽然确实惊喜，里面的纹理，用来做裙子什么的说不定真的可以，但是对于网页背景来说还是相当奢侈的。然后有朋友就提到了用 linear-gradient 来绘制类似的条纹背景，于是就这样做了。

代码实现

在 :root 伪类里面声明 --color-1 ~ 5以及这些个全局变量颜色，随意更改16进制的颜色值，然后就可以更愉快的在其他地方使用啦！或者用JavaScript更改CSS，随机变颜色纹理什么的，都可以！

:root {
  --main-bg-color: #ffe7f4;
      --color-1:#0F217799;
      --color-2:#74BDD599;
      --color-3:#62accc99;
      --color-4:#81dbc899;
      --color-5:#94b0ba99;
}

body {
    background-image: 
      linear-gradient(to right, transparent, transparent 46%, var(--color-1) 46%, var(--color-1) 47%, transparent 47%, transparent),
      linear-gradient(to bottom, transparent, transparent 46%, var(--color-1) 46%, var(--color-1) 47%, transparent 47%, transparent),
      linear-gradient(to right, transparent, transparent 25%, var(--color-2) 25%, var(--color-2) 26%, transparent 26%, transparent),
      linear-gradient(to bottom, transparent, transparent 25%, var(--color-2) 25%, var(--color-2) 26%, transparent 26%, transparent),
      linear-gradient(to right, transparent, transparent 27%, var(--color-2) 27%, var(--color-2) 42%, transparent 42%, transparent),
