Material UI React 应用程序中没有滚动条的全高和宽度

Question

I am trying to render a page for full height. But it adds a scrollbar which is undesirable. With 100% height, I mean just the size of the screen.

Here is the demonstration. The yellow highlighted part is the unwanted height added. There is also a horizontal scrollbar(not highlighted):

Here is the render method of the page:

return (
    <>
        <Box display='flex' flex='1' justifyContent='space-around'>
            <IndexSelector
                id='index'
                value={symbol}
                onChange={this.onSymbolChange}/>
            <SeriesSelector
                id='series'
                seriesList={Form.seriesList}
                onChange={this.onSeriesChange}/>
            <DateRange fromDate={fromDate} toDate={toDate} onChange={this.onDateChange}/>
        </Box>

        <Box height='100%' border='1px solid red' marginTop='50px'>
            <Graph instructions={this.getInstructions()} apiData={this.apiData} />
        </Box>
    </>
)

Here is the index.css:

html {
  box-sizing: border-box;
}

html, body, #root {
  padding: 0px !important;;
  margin: 0px !important;;
  height: 100vh;
  width: 100vw;
}

*, *:before, *:after {
  box-sizing: inherit;
}

body {
  font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", "Roboto", "Oxygen",
    "Ubuntu", "Cantarell", "Fira Sans", "Droid Sans", "Helvetica Neue",
    sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

code {
  font-family: source-code-pro, Menlo, Monaco, Consolas, "Courier New",
  monospace;
}

How to avoid this extra height & width and make the red border boxed container full height?

EDIT : As per @gowatham suggestion, I tried and it didn't work. I got the following result:

Answer 1

Don't give up! CSS styling can be tricky when you first started, but it is actually quite straight forward after you plan your page layout.

I would do 90vh for the body and set 10vh for the filter box that you have above, so it will always be only 100vh on the page, unless you wanted to change the layout. So I would have something like this:

return (
  <div style={{ height: '90vh', margin: 0, padding: 0 }}>
    <Box display='flex' flex='1' justifyContent='space-around' style={{ height: '10vh' }}>
        <IndexSelector
            id='index'
            value={symbol}
            onChange={this.onSymbolChange}/>
        <SeriesSelector
            id='series'
            seriesList={Form.seriesList}
            onChange={this.onSeriesChange}/>
        <DateRange fromDate={fromDate} toDate={toDate} onChange={this.onDateChange}/>
    </Box>

    <Box style={{ maxHeight: "100%", overflow: "auto" }}>
        <Graph instructions={this.getInstructions()} apiData={this.apiData} />
    </Box>
  </div>
)

Note that your border 1px might also increase the 100% and you might see a scrollbar. To force hide the scrollbar, just add overflow: hidden to the parent div. Example on CodeSandbox:

If you set the main container to be 100vh, ie 100% of viewport height, and make it a display its children with a flex column direction, then you can just make the result container take all the remaining space by setting it to flex: 1 and make its content scroll by also setting overflow: auto

The benefit of this approach is that you can let the filter container be of any/dynamic height and it'll still work.

<Box height="100vh" display="flex" flexDirection="column">
  <Box>Filter</Box>
  <Box flex={1} overflow="auto">
    {Array.from(Array(100)).map((v, i) => (
      <div key={i}>Testing {i}</div>
    ))}
  </Box>
</Box>

Another possible solution, that would probably work in ancient browsers as well, is to just set the filter container to position: fixed and then make sure that element that directly follows the filter container has either margin-top or padding-top that is enough to prevent it's content from appearing behind the filter div when the page is scrolled to the top.

<Box
  position="fixed"
  top={0}
  height="60px"
  width="100%"
>
  Filter
</Box>
<Box marginTop="60px">
  {Array.from(Array(100)).map((v, i) => (
    <div key={i}>Testing {i}</div>
  ))}
</Box>

Try subtracting box1 height from box2 height create a ref to box1:

ref={(ref) => this.box1 = ref}

Then in box2:

height={`calc(100% - ${this.box1.clientHeight}px)`}

Like this:

return (
    <>
        <Box display='flex' flex='1' justifyContent='space-around' ref={(ref) => this.box1 = ref}>
            <IndexSelector
                id='index'
                value={symbol}
                onChange={this.onSymbolChange}/>
            <SeriesSelector
                id='series'
                seriesList={Form.seriesList}
                onChange={this.onSeriesChange}/>
            <DateRange fromDate={fromDate} toDate={toDate} onChange={this.onDateChange}/>
        </Box>

        <Box height={`calc(100% - ${this.box1.clientHeight}px)`} border='1px solid red' marginTop='50px'>
            <Graph instructions={this.getInstructions()} apiData={this.apiData} />
        </Box>
    </>

Try to include Flex for the Parent also

<div display='flex' flex='1' height='100%' justifyContent='space-between'> //use flex direction column as per your library     
        <Box display='flex' flex='1' justifyContent='space-around'>
            <IndexSelector
                id='index'
                value={symbol}
                onChange={this.onSymbolChange}/>
            <SeriesSelector
                id='series'
                seriesList={Form.seriesList}
                onChange={this.onSeriesChange}/>
            <DateRange fromDate={fromDate} toDate={toDate} onChange= 
   {this.onDateChange}/>
        </Box>
        <Box>
            <Graph instructions={this.getInstructions()} apiData={this.apiData} />
        </Box>
    </div>

Answer 5

css Use height: '100vh'in parent instead of 100%. 100% take upto max of height of all content. That won't enllarge after that. 100vh is used for vertical height of whole window and also check the overflow-y

Answer 6

I made the navigation division height:15vh the division following it with height:20vh and the last division with height:65vh adding it to 100 vh ie total device height you can change it as per your wish and alter the height of the divisions. The scroll doesnt appear in the desktop view now

Here is the link to the codepen It is responsive for me check whether it works. (Ive used the pastebin code that you have provided with)
