Quick Guide on Flexbox💪💪

Hola Coders!

In this article, we will learn about flexbox in CSS. It is a very easy to learn property of CSS. You will love the flexbox and want to implement it in next CSS styling work.

Now let's start the coding 🙋‍♀️

Axis in Flexbox

Flexbox contains two axis 👇

  • main axis
  • cross axis

main axis

It is the axis in which the items are laid out. It depends on the flex-direction. If flex-direction is row than main-axis is horizontal else if it is column then main axis is vertical

cross axis

The Cross axis is perpendicular to the main axis. The direction of the cross axis depends on the main axis.

By default flex-direction is row

flex-direction

This property specifies the direction of elements in the container and tells the main axis. Values in flex-direction 👇

  • row: It will have main axis from left to right.

Let's write for all flex-direction

<body>
    <div class="container">
        <div class="maroon"></div>
        <div class="green"></div>
        <div class="pink"></div>
    </div>
</body>
/* general css */
body{
  background-color: #d1d1d1;
}

.green {
  background-color: green;
  width: 100px;
  height: 100px;
  margin: 5px;;
}
.pink {
  background-color: pink;
  width: 100px;
  height: 100px;
  margin: 5px;
}
.maroon {
  background-color: maroon;
  width: 100px;
  height: 100px;
  margin: 5px;
}

/* flex property */
.container {
  display: flex;
  flex-direction: row;

for the above👆 examples we assume the main axis is from left to right.

Let's apply multiple properties together

Centering the elements

/* flex property */
.container {
  height: 500px;
  display: flex;
  flex-direction: row;
  /* centers at main axis */
  justify-content: center;
  /* centers at cross axis */
  align-items: center;
  border : 2px black solid
}

order

order helps in reordering the elements in the container as per the requirement. It works on the basis of priority, highest order number element will be place at the end.

.green {
  background-color: green;
  width: 100px;
  height: 100px;
  margin: 5px;
  /* order */
  order : 1;
}
.pink {
  background-color: pink;
  width: 100px;
  height: 100px;
  margin: 5px;
  /* order */
  order: 0
}
.maroon {
  background-color: maroon;
  width: 100px;
  height: 100px;
  margin: 5px;
  /* order */
  order: 3
}

/* flex property */
.container {
  height: 500px;
  display: flex;
  flex-direction: row;
  justify-content: center;
  align-items: center;
  border : 2px black solid
}

align self

align-self property values are similar to align-items with a slight change that align-self property works on the individual element.

.maroon {
  background-color: maroon;
  width: 100px;
  height: 100px;
  margin: 5px;
  /* applying align-self */
  align-self: flex-start;
}

/* flex property */
.container {
  height: 500px;
  display: flex;
  flex-direction: row;
  justify-content: center;
  align-items: center;
  border : 2px black solid
}

flex wrap

flex-wrap comes into the picture when elements do not align in a single row. When elements shrink within the container, flex-wrap spreads out the container. Values for the flex-wrap 👇

  • nowrap: Every item is fit to a single line.

By default flex-wrap property is nowrap

HTML

    <div class="container">
        <div class="maroon"></div>
        <div class="maroon"></div>
        <div class="maroon"></div>
        <div class="maroon"></div>
        <div class="maroon"></div>
        <div class="green"></div>
        <div class="green"></div>
        <div class="pink"></div>
        <div class="pink"></div>
    </div>

CSS

.green {
  background-color: green;
  width: 100px;
  height: 100px;
  margin: 5px;
}
.pink {
  background-color: pink;
  width: 100px;
  height: 100px;
  margin: 5px;
}
.maroon {
  background-color: maroon;
  width: 100px;
  height: 100px;
  margin: 5px;
}

/* flex property */
.container {
  height: 500px;
  display: flex;
  flex-direction: row;
  justify-content: center;
  align-items: center;
  border : 2px black solid;
  /* flex-wrap */
  flex-wrap: nowrap;
}

  • wrap: Items wrap around to additional lines.
/* flex property */
.container {
  height: 500px;
  display: flex;
  flex-direction: row;
  justify-content: center;
  align-items: center;
  border : 2px black solid;
  /* flex-wrap */
  flex-wrap: wrap;
}

  • wrap-reverse: Items wrap around to additional lines in reverse.
    /* flex property */
    .container {
    height: 500px;
    display: flex;
    flex-direction: row;
    justify-content: center;
    align-items: center;
    border : 2px black solid;
    /* flex-wrap */
    flex-wrap: wrap-reverse;
    }

flex flow

flex-flow is the shorthand notation for flex-direction and flex-wrap .

/* flex property */
.container {
  height: 500px;
  display: flex;
  justify-content: center;
  align-items: center;
  border : 2px black solid;
  /* 
  flex-direction : column;
  flex-wrap : wrap;
  */
  flex-flow : column wrap;
}

align content

align-content helps in spacing multiple lines or can say it sets the space between multiple lines.

This can be confusing, but align-content determines the spacing between lines, while align-items determines how the items as a whole are aligned within the container. When there is only one line, align-content has no effect.

  • flex-start: Lines are packed at the top of the container.
    /* flex property */
    .container {
    height: 500px;
    display: flex;
    justify-content: center;
    align-items: center;
    border : 2px black solid;
    flex-flow : row wrap;
    align-content: flex-start;
    }
    

image.png

  • flex-end: Lines are packed at the bottom of the container.
/* flex property */
.container {
  height: 500px;
  display: flex;
  justify-content: center;
  align-items: center;
  border : 2px black solid;
  flex-flow : row wrap;
  align-content: flex-end;
}

image.png

  • center: Lines are packed at the vertical center of the container.
    /* flex property */
    .container {
    height: 500px;
    display: flex;
    justify-content: center;
    align-items: center;
    border : 2px black solid;
    flex-flow : row wrap;
    align-content: center;
    }
    

image.png

  • space-between: Lines display with equal spacing between them.
/* flex property */
.container {
  height: 500px;
  display: flex;
  justify-content: center;
  align-items: center;
  border : 2px black solid;
  flex-flow : row wrap;
  align-content: space-between;
}

image.png

  • space-around: Lines display with equal spacing around them.
/* flex property */
.container {
  height: 500px;
  display: flex;
  justify-content: center;
  align-items: center;
  border : 2px black solid;
  flex-flow: row wrap;
  align-content: space-around;
}
