I like the Ant Design of React and for me it’s very useful. Usually I prefer functionality to a better design and it allows me to achieve a functionality much faster. But when you do something not for yourself, you have a customer and he decides which design better.

The post is not about thinking but about the specific customizing of the Antd control Tabs. I wanted to use it at one page of my personal site. And even I could see that it looks not pretty 🙂

Default code for tabs looks like:

<Tabs defaultActiveKey="1" items={items} type='card' />

You have the Tab functionality, but background color for active tab is white, for non-active grey.

In documentation I could find a control property ‘tabBarStyle’. And with it the Tabs started to look better.

<Tabs defaultActiveKey="1" items={items} type='card' 
    tabBarStyle={{ display: 'flex', 
        justifyContent: 'left', 
        margin: '0px', 
        backgroundColor: "#d0dde1" }} />
Antd tabs customizing

but I couldn’t find the way how to change the styles for the active tab.

With developer tools I could see the html code of the component and I decided to modify its styles with SAAS.

Antd tabs rendering
.experience {
  display: block;
.experience > div:nth-child(1) {
  display: block;
  border-bottom: $bgSelected 5px solid;
.experience > div:nth-child(1) > div > div> div:not([data-node-key=""]) {
  border: none;

.experience > div:nth-child(1) > div > div > div {
  background-color: $bgNonactive;
  border-top-right-radius: 5px ;
  border-top-left-radius: 5px ;
  padding: 3px 10px 3px 10px;
  margin: 0px;
  min-width: 100px;
  width: auto;
  display: block;
  color: $maintTextColor;
  font-weight: normal;
  text-transform: lowercase;
  border-left: $nonActiveLightLinkColor 1px solid;
  border-bottom: $bgSelected 1px solid;
  &:hover { 
    background-color: $bgSelected;

.experience > div:nth-child(1) > div > div> [class*="ant-tabs-tab-active"] {
  border: $nonActiveLightLinkColor 1px solid;
  background-color: $bgNonactive;

Some comments:

div:not([data-node-key=""]) - means ‘for div which contains non empty attribute ‘data-node-key’

.experience > div:nth-child(1) > div > div> [class*="ant-tabs-tab-active"]  - if attribute contains class ‘ant-tabs-tab-active’
