Css Grid is a game-changer for responsive design, allowing you to create complex layouts with ease. It's particularly useful for mobile-first designs, as it enables you to create a single grid system that adapts to different screen sizes.
One of the key benefits of Css Grid is its ability to handle multiple grid tracks and columns. By using the grid-template-columns property, you can define a grid with multiple tracks, each with its own width and layout. This is especially useful for creating layouts with multiple columns, such as a two-column layout for a blog post.
To create a responsive design with Css Grid, you can use the grid-template-areas property to define different areas of the grid. This allows you to create a layout that adapts to different screen sizes, while still maintaining a consistent overall design. For example, you can define a grid with two areas: one for the main content and one for the sidebar.

Responsive Design Basics
A responsive grid system is a must-have for any modern website. It allows your layout to adapt to different screen sizes and devices, ensuring a great user experience.
You can use a responsive grid system to create multi-column layouts, like the list of projects on the Lean Web Club homepage. To do this, you can use simple fractions for your grid sizes, making it easier to calculate the width of each column.
For example, instead of using a 12-column layout, you can use a grid system with 1fr (one fractional unit) columns, which makes it easy to divide things into thirds, fourths, sixths, and so on.
A media query is often used to wrap your grid system, and it's generally started once the viewport is about 40em (or 640px with the default font size).
Mobile-First Progressive Enhancement
Mobile-first progressive enhancement is a key concept in responsive design. It means that your layout is a single-column design by default, and only layers in a grid once the viewport reaches a certain width.
This approach has several benefits. For one, mobile users automatically get a great experience. If someone's on an older browser that doesn't support CSS Grid, they still get something usable, albeit less pretty.
In fact, Jen mentions in the course that mobile-first excels when content planning is the primary task. This is because a single-column design is often the most straightforward way to display content on smaller screens.
A good starting point for a mobile-first grid system is to wrap your grid system in a media query, starting at around 40em (or 640px with the default font size). This allows you to define the grid layout once the viewport reaches this width.
Here are some key steps to follow when implementing mobile-first progressive enhancement:
- Start with a single-column design by default.
- Use a media query to define the grid layout once the viewport reaches a certain width.
- Use CSS Grid properties like grid-template-columns and grid-template-rows to define the grid layout.
- Use the repeat() method to create a grid with multiple columns.
By following these steps, you can create a responsive design that progressively enhances the user experience as the viewport width increases.
Creating a Responsive System
Creating a responsive system is all about creating a grid system that adapts to different screen sizes and devices. A responsive grid system is essential for delivering a great user experience, regardless of how users access your website.
To create a responsive grid system, you can use CSS Grid, which provides a powerful and flexible way to lay out content on the web. CSS Grid is supported by most modern browsers, including Chrome, Firefox, Safari, and Opera.
A responsive grid system should be designed to work on a variety of devices and screen sizes, from mobile phones to desktop computers. To achieve this, you can use media queries to apply different styles and layouts based on the screen size.
One way to create a responsive grid system is to use a mobile-first approach, where the layout is designed for small screens first and then enhanced for larger screens. This approach ensures that your website is accessible and usable on smaller screens, even if the layout is not as complex.
To create a responsive grid container, you can set the box-sizing of the entire display to border-box and then use the grid-template-columns and grid-template-rows properties to define the column and row sizes. You can also use the grid-column and grid-row properties to place child elements into the grid.
Here are some key properties to use when creating a responsive grid system:
- grid-template-columns: defines the column sizes
- grid-template-rows: defines the row sizes
- grid-column: places a child element into a specific column
- grid-row: places a child element into a specific row
- auto-fit: allows the grid to automatically adjust the number of columns based on the content
By using these properties and a mobile-first approach, you can create a responsive grid system that adapts to different screen sizes and devices, providing a great user experience for all users.
Animation
Animation is a crucial aspect of responsive design, allowing you to create visually appealing and engaging experiences for your users.
In CSS Grid, there are 5 animatable grid properties, but as of this writing, only the animation of grid-gap, grid-row-gap, and grid-column-gap is implemented in any of the tested browsers.
Firefox supports the animation of these properties since version 53, while Chrome supports it since version 66.
If you're using Safari, unfortunately, it doesn't support the animation of these properties yet.
Here's a quick rundown of the current state of browser support for CSS Grid animation:
Keep in mind that browser support for CSS Grid animation is constantly evolving, so be sure to check the latest updates before implementing it in your project.
Setting Up the Grid
To set up a CSS Grid, you need to wrap your grid system in a media query, starting at a viewport size of around 40em (or 640px with the default font size).
For your interest: Different Ways to Size Text Css
First, define the element as a grid with the display: grid property using the .row wrapper class.
You can use the grid-template-columns property to set up rows and columns, and the repeat() method to create a 12-column layout with 1fr (one fractional unit) each.
For responsive grids, it's best to use the grid-template-rows property to define a row with a minimum size of 1fr and an auto-sized maximum.
The column-gap property can be used to add spacing between columns, but you can also use utility classes to control the spacing between rows.
Setting up a simple grid container is easy; just write a simple HTML and set up the grid container with CSS by setting the box-sizing of the entire display to border-box.
The grid system comprises the grid container and the grid items, and setting the container's display to grid makes CSS recognize it as a grid container.

Defining Grid Structure
Defining Grid Structure is a crucial step in creating a CSS Grid layout. You specify the rows and columns using the grid-template-rows: and grid-template-columns: properties.

The number of values you specify in these properties automatically arranges the number of boxes to fit the number of rows and columns. For example, specifying 3 values in grid-template-columns: generates 3 columns.
If you specify 3 values in grid-template-columns for 6 boxes, you get 2 boxes per generated column. This is because the extra boxes are distributed across the columns to fill the grid.
Specifying 4 columns, on the other hand, leaves 2 boxes left to be automatically added to the first and second columns.

Grid Properties and Styles
Using :nth-child() can help reduce repetition in your CSS code, especially when styling multiple items in a grid. This pseudo-selector can take an equation, such as :nth-child(2n+2), which targets every second child element.
The :nth-child(n) selector can also be used to style multiple items in a grid by using a formula like 31n + 1. This ensures that the styling applies to specific child elements, in this case, every 31st child plus one.
A fresh viewpoint: Css Selector Every Child Starting from
The formula 31n + 1 targets the 1, 32, and 63 child elements, but the browser stops looping when it realizes there is no 63 child item. This is a useful technique for creating blue full-width panels that appear at the top of the page and are repeated halfway down.
Using the same spacing, but with a different offset, can create different effects. For example, the 16n + 2 formula creates a different pattern of styling compared to the 16n + 10 formula.
A single selector can be used to target multiple items in a grid when they share the same styles. For example, the selector :nth-child(8n) targets items that are 8n apart, including both the left- and right-hand featured boxes.

Grid Units and Sizing
Grid units are the building blocks of a responsive layout. You can use the fractional unit (fr) to make rows and columns more flexible.
To automatically size columns, you can use the grid-template-columns property with a value like 'repeat(3, 1fr)', which sets the columns to be one-third of the available space on larger screens, half on mid-sized screens, and single column on small ones.

Fractional units like 1fr mean "portion of the remaining space", making them friendly in combination with other units.
The fr unit is more responsive than using px, as it makes the rows and columns more flexible.
You can also use the min-content, max-content, and auto keywords to size rows and columns. The difference between these keywords is spelled out in detail, but essentially, min-content is the minimum size of the content, max-content is the maximum size of the content, and auto is like fr units but "loses" the fight in sizing against fr units.
The fit-content() function uses the space available, but never less than min-content and never more than max-content. The minmax() function sets a minimum and maximum value for what the length is able to be.
Here's a summary of the sizing functions:
- fit-content(): uses the space available, but never less than min-content and never more than max-content.
- minmax(): sets a minimum and maximum value for what the length is able to be.
Grid Overflow and Spacing
Grid overflow can be a real pain to deal with, especially when working with CSS Grid. The problem arises when the grid tries to maintain its explicit grid lines, even when the container shrinks, causing horizontal scrolling.
This happens because the browser is trying to honor the explicit grid lines, but the implicit grid is trying to display fewer columns. To fix this, you need to limit the grid line numbers to 1, 2, and 3, or -3, -2, and -1. Any other numbers will cause the browser to get mixed messages and display unwanted columns.
The issue can be further complicated by grid items with explicit grid-column references that lie outside the desired column count. For example, grid-column: span 3 will force the grid to display at least three columns, even if you want it to display two.

Gutters, Gaps & Spaces
Gutters, Gaps & Spaces are crucial in grid layout design. The gap property is a key factor in this aspect.
The gap property specifies both the gap for the rows and the columns. If you want to specify the gap for the rows and the columns differently, you can use the row-gap or column-gap properties.
You can use the row-gap or column-gap properties in different cases, noting that the syntax does not change.

Overflow Side-Scrolling Problems
Overflow side-scrolling problems occur when the grid layout breaks due to explicit grid line numbering that contradicts the implicit grid layout.
At full-width, the grid looks good, but when resized, the layout breaks, causing horizontal scrolling.
The problem arises because the browser honors the explicit grid lines, trying to maintain all five columns, even though the container has shrunk.
This happens because the grid line numbering system explicitly refers to the fifth grid line, contradicting the implicit two-column grid layout.
To display the implicit two-column grid correctly, only grid line numbers 1, 2, and 3, and -3, -2, and -1 are allowed.
However, if any grid item contains grid-column references outside this range, the browser gets mixed messages and displays unwanted columns, causing horizontal overflow.
Grid always defers to the explicit grid when there's a conflict between implicit and explicit columns, leading to CSS data loss.
Using grid line numbers or spans can create explicit columns, which can cause the grid to break if not adjusted accordingly.

Grid Layout and Positioning
Grid layout is a powerful tool for responsive design, allowing you to create complex layouts with ease.
With CSS Grid, you can specify the grid-template-columns property to define the number of columns and their widths, as seen in our example where we used grid-template-columns: repeat(3, 1fr) to create three equal-width columns.
To position elements within the grid, you can use the grid-column and grid-row properties, which allow you to specify the grid cell where an element should be placed.
In our example, we used grid-column: 1 / 3 to place an element in the first two columns of the grid.

Justifying/Aligning Contents
You can use the justify-content property to align all the grids inside the grid container. This property is used for the alignment of all the grids inside the grid container.
The justify-content property can be set to justify the items to wherever you may want them to be. For instance, if you set the property to center, the items will be centered in the container.
A different take: Text Align Justified Css
The align-content property is used to set the alignment of the grid along the block (column) axis. This is opposed to the justify-content property which aligns the grid along the inline (row) axis.
Here are the different values for the align-content property:
You can also use the place-content property to set both the align-content and justify-content properties in a single declaration.
Overlapping Cells
Overlapping cells in a grid layout can be achieved using the overlapping row technique.
The element appearing later in the HTML will be on top when elements overlap in a grid row or column.
Jen uses an overlapping row technique to make a figure's caption overlap the bottom part of an image.
To adjust the caption size, an additional media query is added to the layout.
A CSS Grid layout can be used to overlap two images, and a CSS animation can be added to fade the second image in and out.
Here are some key points to keep in mind when overlapping cells:
- Elements appearing later in the HTML will be on top when overlapping.
- A CSS animation can be used to fade the second image in and out.
- Additional media queries may be needed to adjust the layout.
Overlapping cells can be used to create visually appealing and complex layouts, but it requires careful planning and execution.
Grid Browser Support and Miscellaneous
CSS Grid has been widely adopted, with Chrome supporting it since version 57.
The browser support for CSS Grid is impressive, but it's essential to consider the limitations of older browsers.
Firefox supports CSS Grid since version 52, making it a great option for developers.
IE, unfortunately, only supports CSS Grid in version 11 and up, marked with an asterisk (*), indicating it's a partial support.
Edge supports CSS Grid since version 16, which is great news for Windows users.
Safari has been on the bandwagon since version 10.1, providing a solid foundation for developers working with CSS Grid.
Here's a quick rundown of the browser support for CSS Grid:
