How to customize Ant.design styles

Question

Who knows how to customize Ant.design styles in proper way?

For example, I want to change the default backgroundColor and height of Header section:

import React, { Component } from 'react';
import { Form, Layout } from 'antd';
const { Header, Footer, Sider, Content } = Layout;

export default class Login extends Component {

render () {
    return (
        <div>
            <Layout>
                <Header style={{backgroundColor: '#555555', height: '5vh'}}>header</Header>
                <Layout>
                    <Content>main content</Content>
                </Layout>
                <Footer>footer</Footer>
            </Layout>
        </div>
    )
}
}

Is it ok, or there is a better way to customize styles? Because I have not found some component's attributes or smth. like this.

The original answer was from 2018, a lot has changed since then, please refer to their documentation

As @khetho mtembo said, starting v5 those less variables got removed, v4 less values can be found here

Original answer:

Antd has externized most of their styling variable in LESS variables

as you can see in

https://github.com/ant-design/ant-design/blob/master/components/style/themes/default.less

To be able to overwrite those variables you need to use modifyVar function from LESS

you can find more about theming here

So to your specific question, @layout-header-background does the job
