In this exercise, we will be working with a 5x5 grid and a single pink box:

## Challenge

Your challenge is to manipulate the pink box div so that it matches the target layout:

![screenshot](https://res.cloudinary.com/dwppkb069/image/upload/v1684523230/tutorials/images-16.1_Exercise10_Intro.mp4/161_exercise10_intro_4_00-19560-so-that-it-looks-like-this_bzlgi5.png)

You only need to modify the CSS for the `#pinkbox` div.

Move it around within the grid, adjust its size by changing the number of rows and columns it spans, and try to match the target layout shown above.

Remember, you don't need to touch the HTML file for this exercise. Just focus on styling the pink box div to achieve the desired result.

Test your understanding by reproducing a given layout.

Currently the pink box is positioned in the top left corner of the grid.

We want it to look like this:

![screenshot](https://res.cloudinary.com/dwppkb069/image/upload/v1684523231/tutorials/images-16.2_Exercise10_Solution.mp4/162_exercise10_solution_3_00-17000-so-lets-set-grid-column-start-on-the-pink-box-to-be-line-3_xuwl6j.png)

First, let's move the pink box in the column direction.

Currently, it starts on column line 1, but we want it to start on column line 3. To do this, set the `grid-column-start` on the pink box to be line 3. We also want it to be two columns wide, so we'll set the `grid-column-end` to be line 5:

```css
#pinkbox {
  grid-column-start: 3;
  grid-column-end: 5;
}
```

![row direction screenshot](https://res.cloudinary.com/dwppkb069/image/upload/v1684523230/tutorials/images-16.2_Exercise10_Solution.mp4/162_exercise10_solution_7_00-44000-now-in-the-row-direction--the-row-start-currently-is-line-1-i-want-it-to-start-on-line-2_t10ovr.png)

This moves the pink box to the desired column position.

Now, let's move the pink box in the row direction.

Currently, it starts on row line 1, but we want it to start on row line 2. To do this, set the `grid-row-start` to 2:

```css
.pink-box {
  grid-column-start: 3;
  grid-column-end: 5;
  grid-row-start: 2;
}
```

The boxes have now moved down:

Finally, we need to set where it should end. Since we want the pink box to span across two rows, we'll set the `grid-row-end` to be 5:

```css
.pink-box {
  grid-column-start: 3;
  grid-column-end: 5;
  grid-row-start: 2;
  grid-row-end: 5;
}
```

Now, the pink box is positioned and sized correctly, spanning across multiple columns and rows.

Positioning Across Multiple Rows & Columns with Span

[0:00] Let's get to work. We're going to move this over. Let's go in the column direction first. Right now, it starts on column line one. I want it to start on column line one, two, three. Let's set grid column, start, on the pink box to be line three. That moves it over.

[0:20] Now, what about where it ends, right? It doesn't end at this line. It ends at this line, which would be column line five. Let's set our grid column end to be five. Meaning, it should now span across two columns as it does right there.

[0:37] On the row direction, the row start currently is line one. I want it to start on line two. Let's set grid row, start, to two. That moves it down. Then we need it to end. If this is one, two, three, four, five, on line five. Grid row and five. This is our version. This is the solution we're trying to recreate. Perfect.

[1:08] That's using grid column, start, and end and grid row, start, and end to move something around, but not just move it as a single little tiny box, but also grow it across multiple grid tracks, multiple columns, and multiple rows.

Practice Moving and Spanning Grid Items

[0:00] Next, we've got another exercise with our good friend, the pink box. We still have this five-by-five grid I've already pre-set up for you. You don't need to touch anything in the grid container as you can see here. All that I'd like you to do is move the pink box around and change how many columns and rows it spans so that it looks like this.

[0:20] I'll leave the video on this frame so you can pause and look at this. It's moved over a couple of columns. It's moved down a row. It also spans across multiple rows and multiple columns. This is what we start with. This is what I'd like you to end with. You don't need to touch the HTML file. There's nothing here for you.

[0:39] Just style the pink box div itself. Move it up. Move it down. Move it right and left. Make it fatter, skinnier, taller, whatever you need to do to match what you see right there from this starting state.

Creating CSS layouts that behave as expected no matter the viewport size used to be a frustrating, time-consuming experience.
But thanks to CSS Grid, these headaches are a thing of the past!
Through a series of concise lectures and hands-on exercises, this comprehensive tutorial will guide you through everything you need to know about creating responsive layouts for all of your web applications.

## CSS Grid Basics

Dive right into CSS Grid! You'll learn how to enable grid, define basic layouts, and use DevTools overlays to help plan and debug grid lines and areas.

## Units and Utilities

Pixels are precise, but can lead to annoying calculations. Luckily CSS Grid supports alternatives like percentages and fractional units that can be combined to create more complex layouts without having to do math. Useful shorthand properties and helpful functions are also introduced.
## Positioning Elements by Lines
Learn to take a more specific approach to creating layouts by specifying the lines where elements should be placed.

## Grid Areas

When the layout you're implementing is too complex for specifying lines, grid areas are the way to go. In this section you'll learn to visualize your layout as you create named areas, including support for empty spaces.

## The Implicit Grid

You've seen a few ways to explicitly define layouts. Now it's time to look behind the scenes at the implicit grid. Understanding this behavior allows you to change the default placement algorithm and support dynamic layouts.

## Creating Responsive Grids

Up until now the layouts we've created have been meant for larger computer screens. In this section you'll practice creating grid layouts that seamlessly adjust to different viewport sizes with help from media queries and useful CSS Grid functions.

## Building an Example Layout

To wrap up the CSS Grid tutorial, follow along as a common layout is built step-by-step following the "mobile first" approach.


Learn how to activate CSS Grid for a container element and the difference between 'display: grid' and 'display: inline-grid'.

Enabling CSS Grid

The grid developer tools available in modern browsers allow you to visually inspect your CSS grids with overlays and track lines.

Visualize CSS Grid with DevTools

The `grid-template-columns` property is used to define column widths within a grid container in CSS Grid.

Define CSS Grid Columns with grid-template-columns

Practice defining columns by converting a single-column layout into an evenly sized three-column grid.

Implement a Three-Column Layout

CSS Grid Basics

Using Percentage Units

Percentages are easier than pixels, but even they can reach a limit. Fractional units provide a flexible approach to layouts.

Simplify Grid Layouts with Fraction Units

Create a three-column layout with equal-sized columns and two rows. The top row should be twice as large as the bottom row. The layout should be responsive.


Define a Three-Column, Two-Row Grid

Implement a Layout with Fractional Units

You aren't stuck with just one unit when defining a grid. Mixing units allows for more complex layouts.

Mixing Fractions and Pixels

CSS Grid's `repeat` function is a time saving way to define your layouts.

Simplify Layout Definitions with repeat

Practice using fractional units and the `repeat` function by implementing a checkerboard layout.

Use Fractional Units and repeat to Define a Layout 

Implement a Checkerboard Layout

So far we've been defining rows and columns manually. The `grid-template` shorthand allows us to define both at once.

Save Time with the grid-template Shorthand

CSS Grid supports adding gaps between rows and columns, allowing you to put visual space between elements.

Adding Gaps between Rows and Columns

Units and Utilities

Items in a grid can be positioned based on column and row lines in the grid.

Positioning with Grid Lines

Using the `grid-column-start` property allows you to set where items in the grid should begin.

Specify the Column Start Position 

In this exercise, you'll practice moving an element using line numbers.

Moving an Element to a New Column

Setting an Element's Column Position

Just as you can specify the column start, you can set the row start.

Specify the Row Start Position

In this exercise you are tasked with moving an element to a specific location.

Positioning with grid-column-start and grid-row-start

Practice Positioning Elements

In addition to specifying the start lines, we can specify where an element should end.

Specify the End Line

So far we've been specifying columns and rows manually. CSS Grid offers a shorthand syntax that will save you some keystrokes.

Grid Column and Row Shorthand

Use the grid row and column shorthand to position multiple boxes in a layout.

Practice Shorthand Positioning

The `grid-area` property gives us another way to position an element using grid lines.

Positioning an Element with grid-area

Using the span Keyword to Position Elements

Test what you've learned so far by duplicating a layout using shorthand syntax and the span keyword.

Specific Placement with Shorthand Properties and Span

Until now we've been counting grid numbers. CSS Grid allows you to add names to lines, then position items accordingly.

Customize Grid Line Names

Positioning Elements by Lines

So far we've primarily used numbers when defining layouts. Before we look at an alternative, let's build the layout that will be reproduced.

Building an Example Layout with Numbered Columns and Rows

Using what you've learned so far, practice using CSS Grid to create a web page layout.

Web Page Layout Solution

CSS Grid's `grid-template-areas` property allows you to assign names to the areas between track lines.

Naming Areas of the Grid

Once you've named your grid areas, you can assign elements to use that space.

Assigning Elements to Named Grid Areas

Recreate a layout using named areas instead of line numbers.

Recreate a Layout Using Named Grid Areas

Practice Using Grid Template Areas

From just a visual of a layout, you can reason about how the grid areas should be defined.

Creating a Complex Layout with Grid Areas

CSS Grid allows you to leave an empty space in your grid layout, while specifying how other elements flow.

Leaving Empty Spaces in Grid Template Areas

Grid Areas

So far we've explicitly specified the behavior of our grid layouts. However, there is also implicit grid behavior that affects how content is placed.

Understanding the Implicit Grid in CSS Grid

Test your understanding of the implicit grid by recreating a layout that dynamically supports any number of elements.

Dynamically Setting Row Heights in a Layout

Create a Dynamic Grid with Equally Sized Boxes

The `grid-auto-flow` property can be used to change the default direction of element placement in CSS Grid.

Changing the Default Placement Algorithm

The `dense` modifier keyword tells CSS Grid to pack elements into the grid.

Row Dense and Column Dense Auto Flow

Test your understanding of how to modify the behavior of grid elements.

Grid Direction Exercise

In addition to rows, column behavior in the implicit grid can be modified.

Grid Auto Columns and the Implicit Grid

CSS Grid's `minmax` function allows you to define minimum and maximum sizes for grid items.

Specify Ranges with the minmax Function

Combining `repeat` function works well with `minmax` to define flexible layouts without the constraints of hard-coded values.

Combining minmax with repeat to Define Layouts

Test your understanding by recreating a given layout.

An overview of one of the most common page layouts and how it behaves at different viewport sizes.

Overview of a Common Layout

We'll start by implementing the layout as a mobile-style single column layout.

Defining a Single-Column Layout

Moving on, we'll add a media query to shift the layout to use two columns.

Adding a Two-Column Layout

With the smaller viewport layouts taken care of, we'll implement a layout for large screen sizes.

Adding a Large Screen Layout

In this example we'll look at implementing a responsive layout that supports cards of different sizes without writing media queries.
