You can use external css file and then import it in your code

您可以使用外部 css 文件,然后将其导入到您的代码中

You can also use Inline CSS

您还可以使用内联 CSS

<NavLin / to="/home" activeStyle={{ color:'green', fontWeight: 'bold'}}> Home </NavLin>

Object of style can be populated here

可以在此处填充样式对象

activeStyle={{ color:'green', fontWeight: 'bold'}}

You can do it like below :

你可以这样做:

<h1 style={{color: 'red'}}>Hello world</h1>

React treats style attribute as an object. So we have to provide double quotes "{{ }}" and inside that is our css code. Also the notation should be camel-case. e.g. {{backgroundColor: 'red'}}

React 将样式属性视为一个对象。所以我们必须提供双引号 "{{ }}" 并且里面是我们的 css 代码。符号也应该是camel-case. 例如{{backgroundColor: 'red'}}

style tagin index.html

index.html 中的样式标签

<style>
  .textColor{
     color : 'red'
  }
<style>

Use : <h1 className="textColor">text colors</h1>

用 : <h1 className="textColor">text colors</h1>

Inline:

内联

<h1 style={{ color: 'red' }}>inline styling</h1>

Using Style Object

使用样式对象

const styles= {
    color: 'red',
};
<h1 style={styles}>Style obje</h1>
