How can I prioritize my own stylesheet over Bootstrap in a React project where it is included in the index.js file?

In an attempt to customize the appearance of a Bootstrap component, I am creating my own stylesheet and importing it into my xyz.js file. Here is the setup:

Xyz.js

import React, {Component} from 'react';
import axios from 'axios';
import qs from 'qs';
import '../css/company.css'
export default class Xyz extends Component{ 
    constructor(props){
        .....
    }
    render(){       
        return( 
            <div className="container" style={{float: "left"}}>

                <table className = "table">
                    <tbody>
                        <tr>
                            <td>{this.props.index + 1}</td>
                            <td>{this.props.company.name}</td>
                            <td>{this.props.company.type}</td>
                        </tr>
                    </tbody>
                </table>
            </div>
        )
    }
}

// I am trying to set border-top of <td> to 0px which is set to 1px 
//by default by bootstrap.css but I am not able to do so

xyz.css

td {
    border-top-width: 0px;
    height: 2px;
}

I am trying to customize the border-top property of the 'td' tag to 0px, which is initially set to 1px by the bootstrap.css. However, I seem to be encountering difficulties in achieving this.

Answer №1

CSS determines which rule to apply when there are multiple rules available based on various criteria that are worth further exploration. However, in this scenario, two factors can be beneficial:

  1. Specificity: I encourage you to delve deeper into this concept. Essentially, assigning a class to your td and styling td.classname will elevate the specificity of your rule, allowing it to override the less specific type selector provided by Bootstrap.

  2. !important: By adding !important after your rule, you can ensure it takes precedence over others. It's worth noting that there are additional criteria that determine the order and application of multiple !important rules.

Answer №2

Utilizing the important attribute in your styles is one way to ensure priority.

Alternatively, you can explore the use of styled-components to create custom styles for various tables, like the example below.

import { styled } from 'styled-components';

const UserTD = styled.td`
  border-top-width: 0px;
  height: 2px;
`

<UserTD>{this.props.index + 1}</UserTD>
