First, What is Grid?

Grid is a blueprint for making websites.

The Grid model allows us to layout the content of our website. Not only that, it helps us create the structures needed for creating responsive websites for multiple devices.

Here's a simple demo which I created using Grid as the main blueprint.

Desktop View

Mobile View

Grid Architecture

So how does Grid architecture work? The Grid items [Contents] are distributed along the main axis and cross axis. Using various Grid properties, we manipulate the items to create our website layouts.

By the way, we can join multiple rows and columns, just like Excel software, which gives us more flexibility and options than Flexbox.

Here's a CheatSheet I made for Flexbox

Grid Chart --

This chart contains every possible property you can use when using grid. Grid properties are divided into -

• Parent properties
• Children Properties

Note : The red colored text are the shorthand properties

At the end of this tutorial, You'll have a clear understanding of how to use all of those properties

How to Set Up the Project

For this project, you need to know little bit of HTML, CSS, and how to work with VS code. Follow along with me as we complete the following tasks:

1. Create a folder named "Project-1" & Open VS Code
2. Create index.html and style.css files
3. Install Live Server and run it.

Or, you can just open Codepen and start coding.

At the end of this tutorial, you will be able to make accurate and beautiful website layouts.

And...we're all set! Let's start coding. 😊

HTML

create 3 boxes inside our body tag. Like this 👇

<div class="container">
  <div class="box-1"> A </div>
  <div class="box-2"> B </div>
  <div class="box-3"> C </div>
</div>

CSS

Step-1

Let's clear our default browser styles. Follow me 👇

*{
  margin: 0px;
  padding: 0px;
  box-sizing: border-box;
}

Step-2

Inside the body selector, do these adjustments

body {
  font-family: sans-serif;
  font-size: 40px;
  width: 100%;
  min-height: 100vh;
}

Step-3

Now, Let's style our boxes by selecting all of them together ->

[class^="box-"] {
  background-color: skyblue;

/* To place the letter at the center */
  display: grid;
  place-items: center;
}

Note : Don't worry, we'll discuss about those grid properties in details.

Step-4

Now, place some gap between our boxes like this 👇

.container {
  display: grid;
  gap: 20px;
}

But Wait....

Before starting, you need to understand the relationship between parent & child classes.

For the Grid Parent property, we will write inside .container class. For the Grid Children Property, we will write on .box-* classes

Grid Parent Properties

First, Let's learn The grid Parent properties !

grid-template-columns

This is used to define the Number & Width of columns. You can either individually set the width of each column, or set an uniform width for all columns using "repeat()" function.

To recreate these results, Write on CSS These lines ->

.container {
  display: grid;
  gap: 20px;

/*  Change the values     👇 to experiment */
  grid-template-columns: 200px auto 100px;
}

Note :

• The pixel values will be an exact measurement. The "auto" keyword will cover available space.
• if you use fr (fraction unit) measurement, all the boxes will be equal in size

grid-template-rows

This is used to define the Number & Height of rows. You can either individually set the height of each row, or set an uniform height for all rows using "repeat()" function.

To test these results, Write on CSS These lines ->

.container {
  display: grid;
  gap: 20px;
  height: 100vh;

/* Change the values  👇 to experiment */
  grid-template-rows: 200px auto 100px;
}

grid-template-areas

This is used to specify the amount of space a grid cell should carry in terms of column & row across the parent container. Life's Quite Easier With this as it allows us to see visually what we're doing.

Call it, the blueprint(template) of our layout👇

To experiment with this, you need to understand both the parent and children property -

• grid-template-areas : The parent property who will create the blueprint
• grid-area : the children property who will follow the blueprint.

First, create the blueprint

Like this 👇 inside the parent .container class

.container {
  display: grid;
  gap: 20px;
  height: 100vh;

  grid-template-areas: 
    "A A A A   A A A A   A A A A"
    "B B B B   B B B B   B B C C"
    "B B B B   B B B B   B B C C";
}

Implement the blueprint

Target all our children .box-* classes and set the values like this ->

.box-1{
  grid-area: A;
}
.box-2{
  grid-area: B;
}
.box-3{
  grid-area: C;
}

Note : The grid-area property will be discussed again on the grid children property section

column-gap :

This property is used to place gap between Columns inside the grid 👇

To test This, write 👇

.container {
  display: grid;
  height: 100vh;

  grid-template-columns: 100px 100px 100px;
//Change values👇 to experiment
  column-gap:  50px;
}

Note : column-gap works with grid-template-columns

row-gap :

This property is used to place gap between Rows inside the grid 👇

let's test This 👇

.container {
  display: grid;
  height: 100vh;

  grid-template-rows: 100px 100px 100px;
// Change   👇  values to experiment
  row-gap:  50px;
}

Note : row-gap works with grid-template-rows

justify-items :

This is used to position grid-items (children) inside grid container along the X-Axis[Main Axis]. The 4 values are 👇

If you want to test this, then add 1 more box inside HTML ->

<div class="container">

  <!--Other boxes - A, B, C are here-->

  <div class="box-4"> D </div>
</div>

and in css ->

.container {
  display: grid;
  gap: 50px;
  height: 100vh;

// each box is 200px by 200px
  grid-template-rows: 200px 200px;
  grid-template-columns: 200px 200px;

//  Change values 👇  to experiment
  justify-items : end;
}

align-items :

This is used to position grid-items (children) inside grid container along the Y-Axis[Cross Axis]. The 4 values are 👇

Don't change anything on HTML, write in css ->

.container {
  display: grid;
  gap: 50px;
  height: 100vh;

// each box is 200px by 200px
  grid-template-rows: 200px 200px;
  grid-template-columns: 200px 200px;

//  Change values 👇  to experiment
  align-items: center;
}

justify-content :

This is used to position our grid [Basically everything] inside grid container along the X-Axis[Main Axis]. The 7 values are 👇

Don't change anything on HTML, write in css ->

.container {
  display: grid;
  gap: 50px;
  height: 100vh;

// each box is 200px by 200px
  grid-template-rows: 200px 200px;
  grid-template-columns: 200px 200px;

//  Change  values  👇  to experiment
  justify-content: center;
}

align-content :

This is used to position our grid [Basically everything] inside grid container along the Y-Axis[Cross Axis]. The 7 values are 👇

Don't change anything on HTML, write in css ->

.container {
  display: grid;
  gap: 50px;
  height: 100vh;

// each box is 200px by 200px
  grid-template-rows: 200px 200px;
  grid-template-columns: 200px 200px;

//  Change  values 👇  to experiment
  align-content : center;
}

Take a Break

So far so good! Take a break, You deserve it !

Grid Children Properties

Now, Let's look at grid children properties

The Grid Scale

I made this grid scale to demonstrate the calculations of how rows and columns are joined together. We can use any 1 of the 2 types of measurement -

• The digit [1,2,3,4, etc...]
• the span keyword

You'll get a clear picture of this guide ☝️ when we write code in just a short moment

The illustration below 👇 shows the start & end points of row and column of a single cell.

HTML

To experiment with the grid scale and understand the following properties, make 4 boxes inside body tag -

<div class="container">
  <div class="box-1"> A </div>
  <div class="box-2"> B </div>
  <div class="box-3"> C </div>
  <div class="box-4"> D </div>
</div>

We're gonna utilize the repeat() function. What it does is, it repeats our code to a certain time. Here's an example 👇

grid-template-columns : repeat(5,1fr);

This is ☝️ equivalent to writing this 👇

grid-template-columns : 1fr 1fr 1fr 1fr 1fr ;

A Quick Note :

When we use the fr [ Fraction ] unit, we are dividing the screen area into equal proportions.

  grid-template-columns: repeat(5, 1fr);

this ☝️ code is dividing our screen width into 5 equal parts.

We're set, let's start !

grid-column : start/end

THESE 2 properties are used to join multiple COLUMNS together. It is a shorthand of 2 properties -

• grid-column-start
• grid-column-end

Write these on CSS

.container {
  display: grid;
  gap: 20px;
  height: 100vh;

  grid-template-columns: repeat(12, 1fr);
  grid-template-rows: repeat(12, 1fr);
}

The result -

Here, we are dividing our screen [ both width & height ] into 12 equal parts. 1 box is occupying 1 part or you can call it 1fr [ 1 fraction ]. the remaining 8 fractions along the width are empty.

As we are dealing with children properties, we need to target our .box-* classes like this -

.box-1{}
.box-2{}
.box-3{}
.box-4{}

You can experiment with any 1 or all of these boxes, I'll stick with .box-1

Let's bring our grid scale. we are dealing with columns, just focus on the columns, not rows.

The default scale of every .box-* classes are

grid-column-start : 1;
grid-column-end : 2;

/* The shorthand -> */
 grid-column : 1 / 2

We can write this ☝️ in the span unit as well, like this 👇

grid-column : span 1;

Let's assign the empty 8 fractions to .box-1 like this 👇

.box-1{
grid-column : 1/10
}

The result 👇

A Quick note :

How did i do the calculation? The box-1 occupies 1 box itself. And over that, we are adding more 8 boxes. At the last, must add 1 to indicate the end so, 8+1+1 = 10

Using the Span keyword

If You're confused by the 1st one, you can use this as it is easy to understand.

We need to add 8 boxes to .box-1 which is already occupying 1 box. So, we have to do 8+1 = 9

.box-1{
  grid-column : span 9;
}

This is gonna output the same result

grid-row : start/end

THESE 2 properties are used to join multiple ROWS together. It is a shorthand of 2 properties -

• grid-row-start
• grid-row-end

Let's experiment with it ! Here, I'll stick with .box-1
here's our grid guide. Now, only focus on the row scale, not column.

let's join 9 boxes to .box-1 along the row

Write these 👇

.box-1{
  grid-row : 1/11;
}

The calculation -> .box-1 holds 1 box, and add 9 more boxes, add mandatory 1 at last to indicate the end 9+1+1=11

The alternative 👇 using the span keyword

.box-1{
  grid-row : span 10;
}

The calculation -> .box-1 holds 1 box, and add 9 more boxes
9+1=10

The result so far 👇

grid-area :

At first, we need to setup grid-template-areas ☝️ Once done, we have to specify the names used in parent class inside the children classes, like this👇

Specifying grid-template-areas inside parent container 👇

Like this 👇 inside parent class

.container {
  display: grid;
  gap: 20px;
  height: 100vh;

  grid-template-areas: 
    "A A A A   A A A A   A A A A"
    "B B B B   B B B B   B B C C"
    "B B B B   B B B B   B B C C";
}

specifying the names used in parent container inside children classes with grid-areas👇

Like this 👇 inside children classes

.box-1{
  grid-area: A;
}
.box-2{
  grid-area: B;
}
.box-3{
  grid-area: C;
}

Justify-self :

This is used to position 1 individual grid-item (children) inside grid container along the X-Axis[Main Axis]. The 4 values are 👇

Write these to experiment with the values 👇

.container {
  display: grid;
  gap :25px;
  height: 100vh;

/* // each box has equal size */
  grid-template-rows: 1fr 1fr;
  grid-template-columns: 1fr 1fr;
}

Remember ! This only works on the children classes. So, target any .box-* class. I'll target the 1st box

.box-1 {
/*  Change values 👇  to experiment */
  justify-self : start;  
}

align-self :

This is used to position 1 individual grid-item (children) inside grid container along the Y-Axis[Cross Axis]. The 4 values are 👇

Let's Experiment with the values 👇

.container {
  display: grid;
  gap :25px;
  height: 100vh;

/* // each box has equal size */
  grid-template-rows: 1fr 1fr;
  grid-template-columns: 1fr 1fr;
}

Remember ! This only works on the children classes. So, target any .box-* class. I'll target the 1st box

.box-1 {
/*  Change values 👇  to experiment */
  align-self : start;  
}

Short Hands

Let's look at these Grid Short-Hand Properties -

• place-content
• place-items
• place-self
• grid-template
• gap / grid-gap

place-content :

this is the shorthand of 2 properties -

• align-content
• justify-content

An example

align-content : center;
justify-content : end;

/* The shorthand */
place-content : center / end ;

place-items :

this is the shorthand of 2 properties -

• align-items
• justify-items

An example

align-items : end;
justify-items : center;

/* The shorthand */
place-items : end / center ;

place-self :

this is the shorthand of 2 properties -

• align-self
• justify-self

An example

align-self : start ;
justify-self : end ;

/* The shorthand */
place-self : start / end ;

grid-template :

this is the shorthand of 2 properties -

• grid-template-rows
• grid-template-columns

An example

grid-template-rows : 100px 100px;
grid-template-columns : 200px 200px;

/* The shorthand */
grid-template : 100px 100px / 200px 200px;

gap/grid-gap :

gap & grid-gap are the same thing and does the same work. You can use any 1 of them.

this is the shorthand of 2 properties -

• row-gap
• column-gap

An example

row-gap : 20px ; 
column-gap : 30px ;

/* The shorthand */
gap : 20px  30px;
