Flexbox

It is nothing but CSS. Flexbox makes the developer's life easy and saves a lot of valuable time by writing minimal codes to achieve the desired result instead of writing long codes. The basic use of flexbox is to align the elements to center both vertically and horizontally, reverse the elements, order the elements, etc., all this can be done by writing very few codes using flexbox properties otherwise without flexbox to achieve these results would be a nightmare for a developer. Let's jump on to it.

To work with the flexbox you should have a parent element containing a few child elements. Eg:

<div class="parent">
    <div class="child">Child- One</div>
    <div class="child">Child - Two</div>
    <div class="child">Child - Three</div>
</div>

HTML
