React-Bootstrap causing margins on left and right

问题:

I'm using React-Bootstrap in my React app. It is causing margin on the left and right side. I'm using the following code:

import React, { Component } from "react";
import "react-bootstrap/dist/react-bootstrap.min.js";
import "bootstrap/dist/css/bootstrap.min.css";
import { Grid, Row, Col } from "react-bootstrap";
import MuiThemeProvider from "material-ui/styles/MuiThemeProvider";
import AppBar from "material-ui/AppBar";

<Grid fluid>
   <Row>
      <Col xs={12} md={12}>
        <AppBar title="Title"
         iconClassNameRight="muidocs-icon-navigation-expand-more"/>
       </Col>
   </Row>
   <Row>
       <Col xs={4} md={4}>
          <h1>Hello</h1>
       </Col>
       <Col xs={8} md={8} >
          <h1>Hello World!</h1>
       </Col>
   </Row>
</Grid>

I'm getting the following output:

If I remove xs and md from <Col> then the issue gets fixed.

Importing twitter-bootstrap is causing this issue. If I remove the twitter-bootstrap import then the bootstrap styling doesn't work.

This issue is same as Twitter-Bootstrap's issue, but I'm not able to fix it in React-Bootstrap.

回答1:

I tested your code with a clean react app. The previous suggestions were wrong. You need to set Grid components padding-left and padding-right to 0.

UPDATE: Just setting Grid is not enough. Also need to set margins to 0 of Row and paddings to 0 of Col.

You can achieve this by 3 ways.

1. Way: Add inline style for Grid, Row and Col

<Grid fluid style={{ paddingLeft: 0, paddingRight: 0 }}>
    <Row style={{ margin-left: 0, margin-right: 0 }}>
        <Col style={{ padding-left: 0, padding-right: 0 }}>
            ...
        </Col>
    </Row>
</Grid>

OR

const styles = {
    grid: {
        paddingLeft: 0,
        paddingRight: 0
    },
    row: {
        marginLeft: 0,
        marginRight: 0
    },
    col: {
        paddingLeft: 0,
        paddingRight: 0
    }
};
<Grid fluid style={styles.grid}>
    <Row style={styles.row}>
        <Col style={styles.col}>
            ...
        </Col>
    </Row>
</Grid>

2. WAY: Add a custom class name

//App.css
div.noPadding {
    padding-left: 0;
    padding-right: 0;
}

div.noMargin {
    margin-left: 0;
    margin-right: 0;
}

//App.js
import '/path/to/your/App.css';

render() {
    return (
        <Grid fluid className="noPadding">
            <Row className="noMargin">
                <Col className="noPadding">
                    ...
                </Col>
            </Row>
        </Grid>
    )
}

3. WAY You can globally change Grid, Row and Col components behaviour by overriding components className

//App.css

div.container-fluid {
    padding-left: 0;
    padding-right: 0;
}

div.row {
    margin-right: 0px;
    margin-left: 0px
}

div.col-lg-1,div.col-lg-10,div.col-lg-11,div.col-lg-12,div.col-lg-2,div.col-lg-3,div.col-lg-4,div.col-lg-5,div.col-lg-6,div.col-lg-7,div.col-lg-8,div.col-lg-9,
div.col-md-1,div.col-md-10,div.col-md-11,div.col-md-12,div.col-md-2,div.col-md-3,div.col-md-4,div.col-md-5,div.col-md-6,div.col-md-7,div.col-md-8,div.col-md-9,
div.col-sm-1,div.col-sm-10,div.col-sm-11,div.col-sm-12,div.col-sm-2,div.col-sm-3,div.col-sm-4,div.col-sm-5,div.col-sm-6,div.col-sm-7,div.col-sm-8,div.col-sm-9,
div.col-xs-1,div.col-xs-10,div.col-xs-11,div.col-xs-12,div.col-xs-2,div.col-xs-3,div.col-xs-4,div.col-xs-5,div.col-xs-6,div.col-xs-7,div.col-xs-8,div.col-xs-9 {
    padding-left: 0;
    padding-right: 0;
}

回答2:

The answer above is overkill. This really isn't that complicated. According to the official React Bootstrap documentation on Grid the fluid property can be applied. Here's the description for fluid:

Turn any fixed-width grid layout into a full-width layout by this property. Adds container-fluid class.

Here's what I did and it works perfectly:

<Grid fluid={true}>

回答3:

Really late to the party here; I just wanted to add that in Bootstrap 4, I was able to remove the column margins by adding fluid="true" to the Container and noGutters to the Row, e.g.

<Grid fluid="true">
  <Row noGutters>
    <Col>
      {/* ... <contents> ... */}
    </Col>
  </Row>
</Grid>

Adding fluid only does not seem to be enough. Sample code is untested.

回答4:

EDIT: I changed the row to grid. if that fails, then you need to post more code. is there any other div containers the navbar is inside?

there is a few ways to do this:

grid
{
margin: 0;
}

another way is:

grid
{
padding-right: 0px;
padding-left: 0px;
}
