Lab 14 Display Grid


Goal

Learn

body{
    display:grid;
}

display:grid;

Defines the element as a grid container and establishes a new grid formatting context for its contents. Display Grid is a layout system available in CSS. Unlike Display Flex which only allows control for either rows or columns, Display Grid allows the user to control both rows and columns.

body{
     display:grid;
     grid-template-columns: 40px 15% auto 10rem;
     grid-template-rows:25% 100px auto;
}

grid-template-rows

Defines the rows of the grid with a space-separated list of values. The values represent the track size, and the space between them represents the grid line.

grid-template-columns

Defines the columns of the grid with a space-separated list of values. The values represent the track size, and the space between them represents the grid line.

Values: can be a length, a percentage, or a fraction of the free space in the grid (using the fr unit).

Below is a representation of the display grid properties and values from the code above. The white outline is the edge of the <body> and the white vertical and horizontal lines represent the start and end of each column or row. The green values shown along the bottom and right are the numbers assigned to each horizontal and vertical line that create the grid. These numbers can be referenced with grid-item properties to move and stretch the elements within different cells in the grid.

body{
     display:grid;
     grid-template-columns: 40px 15% auto 10rem;
     grid-template-rows:25% 100px auto;
     gap: 1rem;
}

Defines the gaps (gutters) between rows and columns.

Grid-Item Properties

By default any elements that are direct descendants of the grid container will be assigned a grid cell. The will be ordered from left to right, wrapping to a new row as needed. The placement of individual elements can be changed with the following properties:

.item1{
    grid-column-start:1;
    grid-column-end:4;
    grid-row-start:1;
    grid-row-end:3;
}

Hint: When using the grid-item properties to move elements around there is not a unit assigned.

The properties above define a grid item's location within the grid by referring to specific grid lines (the green numbers in the image above). So if the <body> had a four <div> each with a class such as item-1, item-2, etc... We could use grid-row-start, grid-column-start, grid-row-end, and grid-column-end to move the elements into grid cells they were initially assigned to or multiple cells. Like below:

Display grid - grid-area long hand

.item4{
     grid-column:1/4;
     grid-row:3/4;
}

The code above is a shorter version of the grid-item properties above. When using grid-row and grid-column the grid line values are separated by a slash. The values also go in this order: start/end.

Display grid - grid-area med hand

.item-2{
    grid-area: 1/4/3/5;
}

The code above is the shortest version of the grid-items properties. The values for grid-area are: row-start/column-start/row-end/column-end.

Display Grid - grid-area short hand

Practice

Experiment Try moving the items around the grid using the image above as a guide. Use grid-area, grid-column, grid-row, grid-row-start, grid-column-start, grid-row-end, or grid-column-end to move the items.

HTML

<div class="item-1">Item 1</div> <div class="item-2">Item 2</div> <div class="item-3">Item 3</div> <div class="item-4">Item 4</div>

CSS

.item-1{ background-color:aqua; } .item-2{ background-color:red; } .item-3{ background-color:yellow; } .item-4{ background-color:blue; } body{ display:grid; grid-template-columns: 40px 15% auto 10rem; grid-template-rows:25% 100px auto; color:white; background-color:black; }

Final Steps

Validate your HTML.

Lint your CSS at Jigsaw.w3.org

Now look at GitHub Desktop. You should see all of your files listed out in the left column.

GitHub Desktop files listed

Now you are going to commit your changes.

With all of the files checked. Fill out the Summary field in the bottom left and then click Commit to main.
Committing is staging the files, so they can be pushed to the repository hosted at GitHub.

GitHub Desktop Summary field.

Now you want to push your changes to the Repository. Now if you access the repository from another computer Lab14 will be there. After you push in the top right of the nav it should say "Fetch Origin" instead of "Push Origin"
