A Dip Into CSS Flexbox

Hello Fellow Codenewbies 👋

Recently I learned more about flexbox in CSS.
I will write this topic in several posts as I learn and dive into it 😊


Flexbox is a layout model or displaying items in a single dimension — as a row or as a column.
-- MDN Web Docs

Display Properties In CSS

Elements normally have default display: block or display: inline from browsers.

Block stacks on top of each other.
Including in this element:

  • div, header, footer, main, section, etc.
  • heading (h1 - h6)
  • p

While inline stays within the flow.

  • a
  • strong
  • em
  • span

We can change the behavior of these elements. One of the methods is by setting display: flex on the parent element.

.flex-container {
  display: flex
Enter fullscreen mode Exit fullscreen mode

The parent element is known as flex container, and the elements inside flex container are flex item.

Flex Behaviour

  • display: flex will automatically turn the elements inside the parent element into columns.
  • When the total width of the children is bigger than the width of the parent, they will stretch to fit the horizontal axis of the parent element.

I provide an example below to play with.

Toggle the display: flex in the example and see how the elements inside flex-container behave and try also to play around with the width of the elements.


  • Each element have a default display property, either display: block or display: inline.
  • When we apply display: flex to a parent element, by default, it will turn the elements inside it into columns.

Thank you! 😊
I write based on what I've learned so far.
So CSS grid will be there as soon as I learn it 😄
