Reach the underlying DOM element <input>...</input> using styled-components

I am struggling to make changes to the styling of an <input /> wrapped in a React component using styled components. The style I want to override is visible in Dev Tools here:

.ui.input input {...}

I believe the wrapping component needs to pass the className to the input like this:

<input className = {this.props.className} ..> ... </input>

however, I have not been able to successfully override the style with or without that. Below are some code snippets for reference.

//styled component
const StyledSearch = styled(Searchbar)`
  &.ui.input input{
    border: 0px !important;
  }
`;


class SearchBar extends Component {
...
render() {
const style = {
  display: this.state.showResults ? 'block' : 'none',
  maxHeight: 500,
  overflowY: 'scroll',
};
return (
  <div className="ui search fluid" ref="container">
    <div
      className={`ui icon fluid input ${this.props.loading ? 'loading' : ''}`}>
      <input type="text"
        placeholder={this.props.placeholder}
        onFocus={this.focus}
        className = {this.props.className}
        value={this.props.value}
        onChange={this.props.onChange}/>
      <i className="search icon"></i>
    </div>
    <div
      className="results"
      style={style}>

      {
        this.props.results.map((result, index) => (
            <a
              className="result"
              key={index}
              onClick={this.select.bind(this, result)}>
              <div className="content">
                {
                  result.get('image') ?
                  (
                    <div className="image">
                      <img src={result.get('image')} style={{ maxWidth: 50 }}/>
                    </div>
                  ) : null
                }
                <div className="title">
                  {result.get('title')}
                </div>
                <div className="description">
                  {result.get('description')}
                </div>
              </div>
            </a>
          )
        )
      }
    </div>
  </div>
);}}

Essentially, styled-components generates a unique class name (or a new namespace) for any DOM or React Components that have the styled function applied to them.

This means that when you utilize styled(SearchBar), styled-components encapsulates the SearchBar component and assigns a distinct class name to its root DOM element. This unique class name is then propagated down to descendant DOM elements and components (such as nested div, input, a).

In order for this process to function correctly, the root DOM element must have a configurable className attribute. Consequently, styled-components expects the root DOM element to include ${this.props.className} within its className props. If this configuration is absent, styled-components will not be able to establish a designated namespace for applying specific styles.

Therefore, to implement this technique successfully, it is imperative to set ${this.props.className} as one of the values of the className prop defined on the root div of the SearchBar component.

If direct access to the SearchBar component is unavailable, an alternative approach is to wrap it with an additional component. However, this method incurs the overhead of an extra level in the DOM hierarchy.

Based on my observation, it appears that you need to implement the styles produced by styled-components on the wrapper element. This is necessary because of the specificity of the external style .ui.input input. As a result, we cannot directly apply a new style to the input element since the selector .ui.input input has higher specificity and takes precedence over it. To illustrate this, take a look at this simple CSS demonstration:

.ui.input input {
  border:2px solid red !important;
}

input {
  border: 0px !important;
}
<div class="ui input">
  <input />
</div>

Your situation mirrors this same dilemma. In the provided example below, I've introduced a new component called Wrapper, which comes with the following style definition:

&.ui.input input {
  border: 0px !important;
  font-size: 24px;
}   

This particular style targets the inner input element with greater specificity to override the external styles.

import React from 'react';
import ReactDOM from 'react-dom';
import styled from 'styled-components';

class InputWrapper extends React.Component {

  render() {
     const Wrapper = styled.div`
       &.ui.input input {
         border: 0px !important;
         font-size: 24px;
       }
     `;

    return(
      <Wrapper className="ui input">
        <input type="text" placeholder="Input" />
      </Wrapper>
    )
  }
}


ReactDOM.render(
    <InputWrapper />, 
    document.getElementById("app")
);

For reference, here's a link to a WebpackBin example.

With the current version 4, you can easily accomplish this by:

const Input = styled.input`
  border:2px solid red !important;
`;

This will display as a native input with the SC class name applied.
