我正在尝试使用React在网格中显示一些json数据。这里有一些问题,
1-我使用了.col-md-4,因为我想在行上放置4个元素。如您所见,左侧的间距小于右侧的间距。我给行留了一些边距,但是后来我将display:flex更改为display:block,这使容器变得更糟,我将所有产品都放在一行上。如何将其水平对齐?
2-当我检查页面并选择移动设备(例如Iphone X)时,我看到所有产品都向左对齐。我可以给左边距:10vh;到容器(具有@media屏幕和(最小宽度:320像素){}),但是对齐它们以实现移动视图是正确的方法吗?
3个增减按钮没有水平对齐,我是否应该在下面的“ P”处加上最小高度?
4-我已经在github上上传了它。我应该怎么做才能在链接下的github上运行此页面? https://github.com/rahman23/shoppingdemo.github.io
5-您可以给我任何建议或改进吗?
在这里您将找到所有代码
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import ProductInfo from '../plist.json'
class Products extends React.Component {
constructor(props) {
super(props);
this.state = {
count: 0
};
}
handleIncerement() {
this.setState({
count: this.state.count + 1
});
}
handleDecrement() {
this.setState({
count: this.state.count - 1
});
}
render() {
return (
<div className="container">
<div className="row ">
{ProductInfo.map((postDetail, index) => {
return (
<div className="col-md-4">
<a href="require(`${postDetail.url}`)"><img className="productpic" src={require(`./${postDetail.image}`)} /></a>
<h2 className="display-6"> <a href="{postDetail.url}">{postDetail.name}</a></h2>
<p className="h4">{postDetail.price}</p>
<p>{postDetail.description}</p>
<div className="counter">
<button className="btn btn-info" onClick={() => this.handleIncerement()}>+</button>
<div>{this.state.count}</div>
<button className="btn btn-info" onClick={() => this.handleDecrement()}>-</button>
</div>
</div>
)
})}
</div>
</div>
)
}
}
export default Products

答案 0 :(得分:-1)
嘿,您可以使用以下引导类:
.mx-auto //Align items right
.mr-auto //Align items left
.ml-auto //Align items right
像这样:
<div class="row">
<div class="mr-auto">
<!-- Content -->
</div>
</div>
请记住在使用这些类之前始终使用行类。
