HighWall - A React Component

Since version 0.4.0, this is an ES module (bundled with Rollup), which should work fine with Vite and others.

Summary

CSS height: 100vh is useful when trying to implement native-app-like mobile web application. However, on mobile Safari for example, it does not work as expected.

This "HighWall" is a React component which realizes height: 100vh by measuring viewport's height every window size change.

React version

Since this component uses hook internally, React version has to be greater than 16.8.0.

How to use

Green will fill up the viewport. Of course, you can set your own class like <HighWall className="myClass">.

import {HighWall} from 'HighWall';

const Page: React.FC = () => {
  return (
    <HighWall style={{backgroundColor: 'green'}}>
      <div>Child component</div>
    </HighWall>  
  );
};

These settings will show debug information on head-up display.

<HighWall debug={true}> // show in default position, leftBottom.
<HighWall debug={{ position: HudPosition.rightTop }}>

Advanced

Maybe sometimes you want to set viewport's height to min-height or other properties. This can be realized by setting Fitter function in props.

This sample will set the height to min-height instead of height.

import {HighWall, Fitter} from 'HighWall';

const fitter: Fitter = viewportHeight => ({minHeight: viewportHeight});
<HighWall fitter={fitter}>
</HighWall>
