CSS usage in React.js
This time I will bring you the use of CSS in React.js. What are the precautions for using CSS in React.js?The following is a practical case, let’s take a look.
Inline style (not recommended for web development, but widely used in React-Native)The disadvantage is that animation, pseudo-classes (hover), etc. cannot be usedimport React from 'react';export default class ComponentHeader extends React.Component {
render() { const styleComponentHeader = { header: { backgroundColor: '#333333', color: '#FFFFFF', "padding-top": '15px', paddingBottom: '15px'
}, // 还可以定义其他的样式
}; return ( <header>
<h1 id="这里是头部">这里是头部</h1>
</header>
)
}
}
Expression in inline style: When clicked, padding-top and paddingBottom become larger or smaller
import React from 'react';export default class ComponentHeader extends React.Component {constructor() { super(); this.state = { miniHeader: false
};
}
switchHeader() { this.setState({ miniHeader: !this.state.miniHeader
});
};
render() { const styleComponentHeader = { header: { backgroundColor: '#333333', color: '#FFFFFF', "padding-top": this.state.miniHeader ? '3px' : '15px', paddingBottom: this.state.miniHeader ? '3px' : '15px'
}, // 还可以定义其他的样式
}; return ( <header style={styleComponentHeader.header} onClick={this.switchHeader.bind(this)}>
<h1 id="这里是头部">这里是头部</h1>
</header>
)
}
}
ModularizationFirst npm the following three plug-ins
"babel-plugin-react-html-attrs": "^2.0.0","style-loader": "^0.13.1","css-loader": "^0.25.0"
<h1 id="这里是头部">这里是头部</h1>
<h1 id="这里是头部">这里是头部</h1>
import React from 'react';export default class ComponentFooter extends React.Component {
render() { var footerConvertStyle = { "miniFooter": { "backgroundColor": "#333333", "color": "#ffffff", "paddingLeft": "20px", "paddingTop": "3px", "paddingBottom": "3px"
}, "miniFooter_h1": { "fontSize": "15px"
}
} return ( <footer style={footerConvertStyle.miniFooter}>
<h1 id="这是页脚-nbsp-一般放置版权的一些信息">这是页脚, 一般放置版权的一些信息.</h1>
</footer>
)
}
}Vue.js uses transition animation to create route jump animation
Vue.js route naming and named views
