如何制作响应式组件？

Question

我为主要内容创建了三个子组件（不包括标题和标题）

所以第一个组件没有响应。

代码如下：

<div className="row" style={{marginTop:'30px',}}>
        <div className="col-sm-12 col-md-12 col-lg-12">
        <div className="col-sm-3 col-md-3 col-lg-3" style={{display:'-webkit-inline-box', padding:'0px',}}>
            <label style={{backgroundColor: '#ffffff',margin: '5px 10px 5px 5px', position:'relative', float:'left',}} htmlFor="Airport_List">Airport :</label>
            <select value={this.state.airport} onChange={this.handleAirportChange} className="form-control" style={{width:'140px'}}>
            <option value="London">London</option>
            <option value="Houston">Houston</option>
            <option value="California">California</option>
            <option value="New Delhi">New Delhi</option>
            <option value="Moscow">Moscow</option>
            </select> 

        </div> 

        <div className="col-sm-3 col-md-3 col-lg-3" style={{display:'-webkit-inline-box', padding:'0px',}}>

            <span className="fa fa-plane" style={{padding:'5px',fontSize:'20px',}}></span>
            <label style={{backgroundColor: '#ffffff',margin: '5px 10px 5px 5px',}} htmlFor="Flight No">Flight :</label>
            <input style={{
            width:'150px',
            margin: '0',
            outline: '0',
            border: '1px solid #e6ecf0',
            padding:'5px',
            borderRadius: '3px',backgroundColor:'#ffffff',color: 'rgb(158, 158, 158)',}} onChange={this.handleFlightChange}  type="text" id="flightNo" name="flight_no" className="form__input" placeholder="Flight NO"  required/>

        </div>

        <div className="col-sm-3 col-md-3 col-lg-3">

            <div style={{float:'right', display:'-webkit-inline-box',margin:'5px',}}>

            <label style={{backgroundColor: '#ffffff',margin: '5px 6px 5px 5px',}} htmlFor="Date">Date :</label>
            <div className='input-group date' id='datetimepicker8' style={{left:'12px',}}>
            <DateTimePicker 
              onChange={this.onDateChange}
              value={this.state.date}
              minDate={new Date()} 
              name="datetime"

            />
            </div>
            </div> 
        </div>
        <div className="col-sm-2 col-md-2 col-lg-2">

          <Button variant="contained" color="primary" style={{width:'100px', fontSize:'12px'}} onClick={this.handleSubmit}>
               Fetch
          </Button>

         </div>

         <div className="col-sm-1 col-md-1 col-lg-1">

            <div style={{position:'relative', bottom: '10px',}}>
           <Fab color={this.state.color} onClick={()=>this.RecordAudio(this.state.color)}>
             {this.state.icon}
           </Fab>
           </div> 

         </div> 

        </div>

对于日期，我使用了 react-datetime-picker(Link)

所以在全屏时它是这样的

但如果缩小浏览器屏幕，它会变成这样：

这在以前从未发生过。

确保您拥有适当版本的引导程序，并确保您的头脑中有此元标记

我重构了你的代码，如下所示

<div className="row" style={{marginTop:'30px',}}>
    <div className="col-sm-6 col-md-3 col-lg-3" style={{display:'-webkit-inline-box', padding:'0px',}}>
        <label style={{backgroundColor: '#ffffff',margin: '5px 10px 5px 5px', position:'relative', float:'left',}} htmlFor="Airport_List">Airport :</label>
        <select value={this.state.airport} onChange={this.handleAirportChange} className="form-control" style={{width:'140px'}}>
          <option value="London">London</option>
          <option value="Houston">Houston</option>
          <option value="California">California</option>
          <option value="New Delhi">New Delhi</option>
          <option value="Moscow">Moscow</option>
        </select>
    </div>

    <div className="col-sm-6 col-md-3 col-lg-3" style={{display:'-webkit-inline-box', padding:'0px',}}>
      <span className="fa fa-plane" style={{padding:'5px',fontSize:'20px',}}> </span>
      <label style={{backgroundColor: '#ffffff',margin: '5px 10px 5px 5px',}} htmlFor="Flight No">Flight :</label>
      <input style={{
        width:'150px',
        margin: '0',
        outline: '0',
        border: '1px solid #e6ecf0',
        padding:'5px',
        borderRadius: '3px',backgroundColor:'#ffffff',
        color: 'rgb(158, 158, 158)',}}  
        onChange={this.handleFlightChange}  
        type="text" 
        id="flightNo" 
        name="flight_no" 
        className="form__input" 
        placeholder="Flight NO"  required/>
    </div>

    <div className="col-sm-6 col-md-3 col-lg-3">

    <div style={{float:'right', display:'-webkit-inline-box',margin:'5px',}}>

        <label style={{backgroundColor: '#ffffff',margin: '5px 6px 5px 5px',}} htmlFor="Date">Date :</label>
        <div className='input-group date' id='datetimepicker8' style={{left:'12px',}}>
          <DateTimePicker
            onChange={this.onDateChange}
            value={this.state.date}
            minDate={new Date()}
            name="datetime"
          />
        </div>
      </div>
    </div>

    <div className="col-sm-4 col-md-2 col-lg-2">
      <Button variant="contained" color="primary" style={{width:'100px', fontSize:'12px'}} onClick={this.handleSubmit}>Fetch</Button>
    </div>

    <div className="col-sm-2 col-md-1 col-lg-1">
      <div style={{position:'relative', bottom: '10px',}}>
        <Fab
          color={this.state.color}
          onClick={() => this.RecordAudio(this.state.color)}
        >{this.state.icon}</Fab>
      </div>
    </div>
</div>
