Setup 🔥

Open Codepen / any code editor and place these 👇

SCSS

// Defining Break-Points

$bp : (
  mobile  : 480px,
  tablet  : 768px,
  desktop : 1440px,
);

//Defining our Conditional Media query Mixins.
//To save Time & Coffee.

@mixin query($screen){
  @each $key,$value in $bp{

    //  defining max-width

    @if ($screen == $key) {
      @media (max-width : $value){@content};
    }
  }
}

Again .......

//Changing The Default Settings..

*{
  margin: 0px;
  padding: 0px;
  box-sizing: border-box;
  body{
    font-family: sans-serif;
    font-size:30px;
  }
}

//Defining settings of all .box- classes with
//Border color & placing text at Center.

[class ^="box-"]{
  display: grid;
  place-items: center;

//Set any color you wish for testing purposes.
  border : 3px solid red;
}

Level-1

A beginner Friendly Level XD

HTML

<div class="container">
  <div class="box-1">Header</div>
  <div class="box-2">Main</div>
  <div class="box-3">Footer</div>
</div>

SCSS

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

// The Main Sauce. It means, define --
// [.box-1 auto] [.box-2 1fr unit] & [.box-3 auto]

  grid-template-rows: auto 1fr auto;

//Defining gap between rows.
  grid-gap: 10px;
}

level-2

HTML

<div class="container">
  <div class="box-1">Left</div>
  <div class="box-2">Right</div>
</div>

SCSS

For Large Screen

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

// Dividing the Width of screen
// in 12 equal fractions.

  grid-template-columns: repeat(12,1fr);
  grid-gap: 10px;
}

There's confusion in picking number of columns to cover with grid-columns. No need to panic. Just add 1. For this case, we want .box-1 to cover 4 columns. so, we write 1/5. Like this 👇

.box-1{

// Cover 4 columns. 
//So, start = 1 || end = 4+1 = 5;
// grid-column : start/end; 👈 Short-Hand

  grid-column: 1/5;
}

.box-2{

// Cover remaining columns. 
//This value 👇 is taken from .box-1 ☝️
//So, start = 5 || end = 12+1 = 13;
// grid-column : start/end; 👈 Short-Hand

  grid-column: 5/13;
}

For Mobile Screen

// The Media query mixin we defined at start.
//Took (mobile) 👇 from $bp;
@include query(mobile){
  .container{

// Defining that, make the column 1 piece/100%;
    grid-template-columns : 100%; //or, write 1fr

//Defining that, make 2 rows, 1fr (fraction) each,
    grid-template-rows : repeat(2,1fr);
  }

// To remove the previously defined values 
  .box-1,.box-2{
//inherit defines the original value.
    grid-column: inherit;
  }

}

Let's Change the Game with Grid-template areas 😎

Life's Quite Easier With Grid-Template-Areas tbh. It allows us to see visually what we're doing.

Level-3

HTML

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

SCSS

For Larger Screen

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

// Creating a 12 column X 3 row grid 👇

// Defining that 'a' takes 12 columns & 1 row ||'b' takes 8 columns, 2rows || 'c' takes 4 columns, 2rows,
// There is a high chance to get lost here,
// so, divide the areas in 3 columns with blank spaces 👇

  grid-template-areas:
    "a a a a    a a a a    a a a a"
    "b b b b    b b b b    c c c c"
    "b b b b    b b b b    c c c c";
  grid-gap: 10px;
}

.box-1{
  grid-area: a;
}
.box-2{
  grid-area: b;
}
.box-3{
  grid-area: c;
}

For Mobile Screen

@include query(mobile){
  .container{
  grid-template-areas:

    "a a a a    a a a a    a a a a"
    "a a a a    a a a a    a a a a"

    "b b b b    b b b b    b b b b"
    "b b b b    b b b b    b b b b"
    "b b b b    b b b b    b b b b"

    "c c c c    c c c c    c c c c";
  }
}

    "c c c c    d d d d    e e e e";

  grid-gap: 20px;

}
.box-3{

If you prefer to work mobile-first, change mixin's max-width to min-width:

@mixin query($screen){
  @each $key, $value in $bp {

    //  defining min-width
    @if ($screen == $key) {
      @media (min-width : $value) { @content };
    }
  }
}

[Ross A. Smith]

In the Level 5 section, "For Mobile Screen" block the grid-template-areas rule should have the line with all Cs come after the last line of Ds to properly create the layout you've shown in the image.

[Joy Shaheb]

I didn't notice that flaw. Thank you soo much for the feedback. Have a nice day & happy coding ❤️😄
