# Use Hex Code to Color Elements Green

说明：

```
记住 hex code 遵循 red-green-blue（红-绿-蓝），或称为 rgb 格式。hex code 中的前两位表示颜色中红色的数量，第三四位代表绿色的数量，第五六位代表蓝色的数量。

所以要得到绝对的纯绿色，你只需要在第三和第四位使用 F （最大可能的数值），且在其它位使用 0 （最小可能数值）。

通过对 background-color 应用 hex code 值 #00FF00 以把 body 元素的背景色设置为绿色。
```

原始代码：

```
<style>
  body {
    background-color: #FF0000;
  }
</style>
```

调试代码：

```
<style>
  body {
    background-color: #00FF00;
  }
</style>
```
