force css grid container to fill full screen of device

Html Problem Overview

How do I force a css grid container take the full width and height of the device screen for a single page app? Modified example is from Mozilla: Firefox documentation

.wrapper {
  display: grid;
  border-style: solid;
  border-color: red;
  grid-template-columns: repeat(3, 1fr);
  grid-template-rows: repeat(3, 1fr);
  grid-gap: 10px;
}
.one {
  border-style: solid;
  border-color: blue;
  grid-column: 1 / 3;
  grid-row: 1;
}
.two {
  border-style: solid;
  border-color: yellow;
  grid-column: 2 / 4;
  grid-row: 1 / 3;
}
.three {
  border-style: solid;
  border-color: violet;
  grid-row: 2 / 5;
  grid-column: 1;
}
.four {
  border-style: solid;
  border-color: aqua;
  grid-column: 3;
  grid-row: 3;
}
.five {
  border-style: solid;
  border-color: green;
  grid-column: 2;
  grid-row: 4;
}
.six {
  border-style: solid;
  border-color: purple;
  grid-column: 3;
  grid-row: 4;
}

<html>
<div class="wrapper">
  <div class="one">One</div>
  <div class="two">Two</div>
  <div class="three">Three</div>
  <div class="four">Four</div>
  <div class="five">Five</div>
  <div class="six">Six</div>
</div>
</html>

I'm not sure what to do to get this code to work. Any ideas/suggestions would be appreciated.

If you take advantage of width: 100vw; and height: 100vh;, the object with these styles applied will stretch to the full width and height of the device.

Also note, there are times padding and margins can get added to your view, by browsers and the like. I added a * global no padding and margins so you can see the difference. Keep this in mind.

*{
  box-sizing: border-box;
  padding: 0;
  margin: 0;
}
.wrapper {
  display: grid;
  border-style: solid;
  border-color: red;
  grid-template-columns: repeat(3, 1fr);
  grid-template-rows: repeat(3, 1fr);
  grid-gap: 10px;
  width: 100vw;
  height: 100vh;
}
.one {
  border-style: solid;
  border-color: blue;
  grid-column: 1 / 3;
  grid-row: 1;
}
.two {
  border-style: solid;
  border-color: yellow;
  grid-column: 2 / 4;
  grid-row: 1 / 3;
}
.three {
  border-style: solid;
  border-color: violet;
  grid-row: 2 / 5;
  grid-column: 1;
}
.four {
  border-style: solid;
  border-color: aqua;
  grid-column: 3;
  grid-row: 3;
}
.five {
  border-style: solid;
  border-color: green;
  grid-column: 2;
  grid-row: 4;
}
.six {
  border-style: solid;
  border-color: purple;
  grid-column: 3;
  grid-row: 4;
}

<html>
<div class="wrapper">
  <div class="one">One</div>
  <div class="two">Two</div>
  <div class="three">Three</div>
  <div class="four">Four</div>
  <div class="five">Five</div>
  <div class="six">Six</div>
</div>
</html>

Two important CSS properties to set for full height pages are these:

Allow the body to grow as high as the content in it requires.
```
 html { height: 100%; }
```
Force the body not to get any smaller than then window height.
```
 body { min-height: 100%; }
```

What you do with your gird is irrelevant as long as you use fractions or percentages you should be safe in all cases.

Have a look at this common dashboard layout.

Solution 3 - Html

You can add position: fixed; with top left right bottom 0 attribute, that solution work on older browsers too.

If you want to embed it, add position: absolute; to the wrapper, and position: relative to the div outside of the wrapper.

.wrapper {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;

  display: grid;
  border-style: solid;
  border-color: red;
  grid-template-columns: repeat(3, 1fr);
  grid-template-rows: repeat(3, 1fr);
  grid-gap: 10px;
}
.one {
  border-style: solid;
  border-color: blue;
  grid-column: 1 / 3;
  grid-row: 1;
}
.two {
  border-style: solid;
  border-color: yellow;
  grid-column: 2 / 4;
  grid-row: 1 / 3;
}
.three {
  border-style: solid;
  border-color: violet;
  grid-row: 2 / 5;
  grid-column: 1;
}
.four {
  border-style: solid;
  border-color: aqua;
  grid-column: 3;
  grid-row: 3;
}
.five {
  border-style: solid;
  border-color: green;
  grid-column: 2;
  grid-row: 4;
}
.six {
  border-style: solid;
  border-color: purple;
  grid-column: 3;
  grid-row: 4;
}

<html>
<div class="wrapper">
  <div class="one">One</div>
  <div class="two">Two</div>
  <div class="three">Three</div>
  <div class="four">Four</div>
  <div class="five">Five</div>
  <div class="six">Six</div>
</div>
</html>

If you want the .wrapper to be fullscreen, just add the following in the wrapper class:

position: absolute; width: 100%; height: 100%;

You can also add top: 0 and left:0
