Quick start about CSS Flexbox

Here is a brief tutorial on how to use CSS Flexbox to create flexible and responsive layouts:

Flexbox is a layout module in CSS3 that makes it easy to create flexible and responsive designs. It allows you to align and distribute elements within a container, and also provides a convenient way to handle elements with different sizes and aspect ratios.

First, you will need to create a container element and set its display property to “flex”. This will make all direct children of the container flex items.

.container {
  display: flex;
}

You can then use the flex-direction property to control the direction of the flex items. The default value is “row”, which aligns the items horizontally from left to right. You can also set it to “column” to align the items vertically from top to bottom.

.container {
  display: flex;
  flex-direction: row;
}

The justify-content property is used to align the flex items along the main axis (horizontally for row, vertically for column). You can set it to “flex-start”, “center”, “flex-end”, “space-between”, or “space-around” to control the spacing.

.container {
  display: flex;
  flex-direction: row;
  justify-content: center;
}

The align-items property is used to align the flex items along the cross axis (vertically for row, horizontally for column). You can set it to "flex-start", "center", "flex-end", "baseline", or "stretch" to control the alignment.

.container {
  display: flex;
  flex-direction: row;
  justify-content: center;
  align-items: center;
}

You can also control the size and spacing of individual flex items using the flex-grow, flex-shrink, and flex-basis properties. For example, to make an item take up twice as much space as other items, you can set its flex-grow property to 2.

.item {
  flex-grow: 2;
}

This is just a basic overview of how to use Flexbox for creating responsive and flexible layouts. There are many other properties and techniques you can use to create more advanced designs, such as using media queries to change the layout at different screen sizes.

Also, you can use some css frameworks like Bootstrap, Bulma, Foundation, etc. that already have flexbox classes and make layout creation more easy.

I hope this tutorial helps you get started with using Flexbox in your CSS layouts!
