设置线性渐变的高度和宽度 [英] Setting linear gradient height AND width

问题描述

我知道您可以使用设置线性渐变的宽度

I am aware that you can set the width of a linear gradient using

    .grey-block { background: linear-gradient(to right, #f9f9f9 0%, #f9f9f9 35%, white 35%, white 100%); }

以及高度

    .grey-block { background: linear-gradient(to bottom, #f9f9f9 0%, #f9f9f9 65%, white 65%, white 100%); }

但是，有没有一种方法可以使用同一条CSS线同时设置高度和宽度?

However, is there a way you can set BOTH the height and the width using a the same css line?

推荐答案

为澄清起见，问题中的代码不设置 height 和 width 的渐变.它正在调整色标，从而产生一个灰色矩形.

To clarify, the code in the question is not setting the height and width of the gradient. It's adjusting the color stops, which results in a grey rectangle.

为了调整渐变的实际尺寸，我们需要使用 background-size 属性(以及 background-repeat )来设置渐变的高度和宽度.

In order to adjust the actual dimensions of the gradient, we need to use the background-size property (as well as background-repeat) to set the height and width of the gradient.

使用 background-size 控制渐变的尺寸，我们可以将CSS重写如下:

With background-size in control of the gradient's dimensions, we can rewrite the CSS to be as follows:

.grey-block {
  background-color: white;
  background-image: linear-gradient(#f9f9f9, #f9f9f9);
  background-size: 35% 65%;
  background-repeat: no-repeat;
}

正在发生的是，我们正在定义纯色的渐变"并限制其大小. background-repeat (背景重复)已禁用，因此它将仅呈现单个灰色块.

What's happening is that we're defining a "gradient" of a solid color and confining it's size. The background-repeat is disabled so that it will only render a single grey block.

.grey-block {
  background-color: white;
  background-image: linear-gradient(#f9f9f9, #f9f9f9);
  background-size: 35% 65%;
  background-repeat: no-repeat;
}


/* non-relevant styles */
body {
  background-color: #222;
}
.grey-block {
  height: 200px;
  width: 200px;
}

<div class="grey-block"></div>
