How to Make a Simple Website Layout with CSS Grid

CSS Grid has changed how we design websites. It's a really great way to make complex layouts easily. In this guide, you'll learn how to make a CSS Grid layout, from the basics to the more advanced stuff. Whether you're new to this or you've been doing front-end development for a while, this article will give you the info and tools you need to build awesome, responsive websites using CSS Grid. This guide is made to be easy to follow. You'll be able to use CSS Grid in your web design projects right away.

What is CSS Grid?

CSS Grid Layout, or just CSS Grid, is a way to set up webpages in two dimensions. It lets you split a page into rows and columns. This gives you a lot of control over where things go and how big they are. Other ways to do layouts, like floats or flexbox, are mostly one-dimensional. But CSS Grid is great at making complex, responsive layouts with less code. Knowing CSS Grid is super important for today's web design and front-end development.

Why Use CSS Grid?

Two-Dimensional Control: Make layouts with rows and columns. It's more flexible than flexbox.
Responsive Design: Make your layouts fit different screen sizes using media queries. This is a must for responsive design.
Simplified Code: Build complex layouts with less code than older methods.
Order Independence: Change how things look without changing the HTML.
Alignment and Spacing: Control exactly how things line up and how much space is around them.

Setting Up Your First CSS Grid

Let's start with the basics of how to make a CSS Grid layout. We'll make a simple layout with a header, sidebar, main area, and footer. First, we need some HTML:

<div class="container"> <header>Header</header> <aside>Sidebar</aside> <main>Main Content</main> <footer>Footer</footer> </div>

Now, let's add the CSS:

.container { display: grid; grid-template-columns: 200px 1fr; grid-template-rows: 50px 1fr 50px; grid-template-areas: "header header" "sidebar main" "footer footer"; height: 100vh; } header { grid-area: header; background-color: #eee; text-align: center; padding: 10px; } aside { grid-area: sidebar; background-color: #ddd; text-align: center; padding: 10px; } main { grid-area: main; background-color: #ccc; padding: 10px; } footer { grid-area: footer; background-color: #bbb; text-align: center; padding: 10px; }

What's going on here?

display: grid; makes the container a grid.
grid-template-columns: 200px 1fr; makes two columns. The first is 200px wide. The second takes up the rest of the space (1fr means one fraction).
grid-template-rows: 50px 1fr 50px; makes three rows. The first and last are 50px tall. The middle row takes up the rest.
grid-template-areas sets up the layout using names. This makes the code easier to read.
grid-area puts each element in its spot.

Understanding Grid Properties

To use CSS Grid well, you need to know the different properties. Let's look at some of the important ones.

Grid Container Properties

display: grid;: This says the element is a grid container.
grid-template-columns:: This sets how many columns there are and how big they are. You can use fixed sizes (like 200px), percentages (like 50%), fractions (like 1fr), or auto.
grid-template-rows:: This is like grid-template-columns, but for rows.
grid-template-areas:: This sets up the layout with names. It makes the code easier to read and change.
grid-gap:: This sets the space between rows and columns. It's a shortcut for grid-row-gap and grid-column-gap.
grid-row-gap:: This sets the space between rows.
grid-column-gap:: This sets the space between columns.
justify-items:: This lines up grid items on the row axis. You can use start, end, center, or stretch (which is the default).
align-items:: This lines up grid items on the column axis. You can use start, end, center, or stretch (the default).
justify-content:: This lines up the grid itself on the row axis when the items don't take up all the space.
align-content:: This lines up the grid itself on the column axis when the items don't take up all the space.
grid-auto-rows:: This sets the size of rows that are made automatically. These are rows that show up when you put things outside the grid you set up.
grid-auto-columns:: This is like grid-auto-rows, but for columns.
grid-auto-flow:: This says how things should be put into the grid automatically. You can use row (the default), column, or dense.

Grid Item Properties

grid-column-start:: This says where a grid item starts in the columns.
grid-column-end:: This says where a grid item ends in the columns.
grid-row-start:: This says where a grid item starts in the rows.
grid-row-end:: This says where a grid item ends in the rows.
grid-column:: This is a shortcut for grid-column-start and grid-column-end (like grid-column: 1 / 3;).
grid-row:: This is a shortcut for grid-row-start and grid-row-end (like grid-row: 1 / 3;).
grid-area:: This gives a grid item a name. Then you can use that name in grid-template-areas.
justify-self:: This lines up a grid item on the row axis. It overrides justify-items from the grid container.
align-self:: This lines up a grid item on the column axis. It overrides align-items from the grid container.

Using `fr` Units

The fr unit is really useful in CSS Grid. It means a fraction of the space in the grid. This makes it easy to make layouts that stretch and shrink. For example, if you have grid-template-columns: 1fr 2fr;, the first column takes up one-third of the space, and the second takes up two-thirds.

Here's an example:

.container { display: grid; grid-template-columns: 1fr 2fr 1fr; grid-gap: 10px; } .item { background-color: #eee; padding: 20px; text-align: center; }

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

In this example, the grid has three columns. The first and third columns each take up one-quarter of the space. The second column takes up half.

Creating Responsive Layouts with CSS Grid

One of the best things about CSS Grid is that it can make responsive design layouts. You can use media queries to change the grid layout for different screen sizes. This makes your website look great on all devices.

Here's how to use media queries with CSS Grid:

.container { display: grid; grid-template-columns: 1fr; grid-gap: 10px; } @media (min-width: 768px) { .container { grid-template-columns: 1fr 1fr; } } @media (min-width: 992px) { .container { grid-template-columns: 1fr 1fr 1fr; } }

Here, the grid starts with one column for small screens. When the screen gets bigger, it changes to two columns for medium screens, and three columns for large screens.

Advanced CSS Grid Techniques

Once you know the basics of CSS Grid, you can try more advanced ways to make even more complex layouts.

Using `minmax()` Function

The minmax() function lets you set a minimum and maximum size for grid rows or columns. This is good for making layouts that change based on how much content there is.

.container { display: grid; grid-template-columns: minmax(200px, 1fr) 2fr; grid-gap: 10px; } .item { background-color: #eee; padding: 20px; text-align: center; }

In this example, the first column is at least 200px wide, and at most one fraction of the space. The second column takes up two fractions of the space.

Using `repeat()` Function

The repeat() function lets you repeat a grid row or column many times. This is good for making grids with lots of rows or columns that are all the same size.

.container { display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); grid-gap: 10px; } .item { background-color: #eee; padding: 20px; text-align: center; }

Here, the auto-fit keyword tells the grid to repeat the column as many times as it can to fill the space. Each column is at least 200px wide, and at most one fraction of the space.

Naming Grid Lines

You can give names to grid lines to make your code easier to read. This is especially helpful for complicated layouts.

.container { display: grid; grid-template-columns: [sidebar-start] 200px [sidebar-end main-start] 1fr [main-end]; grid-template-rows: [header-start] 50px [header-end content-start] 1fr [content-end footer-start] 50px [footer-end]; grid-gap: 10px; } header { grid-column: sidebar-start / main-end; grid-row: header-start / header-end; } aside { grid-column: sidebar-start / sidebar-end; grid-row: content-start / content-end; } main { grid-column: main-start / main-end; grid-row: content-start / content-end; } footer { grid-column: sidebar-start / main-end; grid-row: footer-start / footer-end; }

In this example, we named the grid lines for the header, sidebar, main content, and footer. This makes it much easier to see how everything is positioned.

Best Practices for CSS Grid Layouts

When you're using CSS Grid, it's good to follow some rules to make sure your layouts work well, are easy to change, and are accessible.

Use Good Class Names: Give your elements names that make sense.
Keep Your HTML Clear: Use the right HTML elements to set up your content.
Test on Different Devices: Make sure your layout looks good on all kinds of screens.
Use Comments: Add notes to your CSS to explain what you're doing.
Validate Your Code: Use a CSS checker to find mistakes.
Make it Fast: Keep your CSS and HTML as short as possible to help the page load quickly.

CSS Grid vs. Flexbox

Both CSS Grid and Flexbox are good for layouts, but they're for different things. CSS Grid is better for layouts with rows and columns. Flexbox is better for lining things up in a row or a column. Knowing what each one does best will help you choose the right one.

Here's a quick look:

CSS Grid: Good for two-dimensional layouts with rows and columns.
Flexbox: Good for one-dimensional layouts, like lining things up in a row or column.

You can even use CSS Grid and Flexbox together to make really complex layouts. You might use CSS Grid for the main page layout, and Flexbox to line things up inside the grid.
