Cheat sheet for Flexbox

In this article, I'll give you some CSS Flexbox basics cheat sheets so you can make your own responsive sites. I'll explain how each of Flexbox's properties work, and I'll give you a cheatsheet that covers everything you can do with Flexbox. Let's Go

Firstly we shall understand, what is flex box? Flex box layout provides us a more efficient way to manage items of a particular container. Flex box layout align, shrink items or make space among items by occupying the given space, and make the website responsive.

Next basics syntax to use flex box Well to use flex box you just have to set container element's display property to flex. display: flex; will enable all flex box feature to this container.

.container{
    display: flex;
}

flex-direction
flex-wrap
justify-content
align-content
align-items
align-self

flex-direction property

This property allows us to set the direction and orientation in which our flex-items should be distributed inside the flex-container.

HTML In HTML, write these lines of code inside the body tag

<div class="container">
        <div class="box-1"><img src="./images/1657573685244Custom Size – 1.png" alt="" srcset="" width="60" height="60"></div>
        <div class="box-2"><img src="./images/download.png" alt="" srcset="" width="60" height="60"></div>
        <div class="box-3"><img src="./images/download1.png" alt="" srcset="" width="60" height="60"></div>
    </div>

CSS Target the .container class and all the boxes. Then style the boxes so that all of them look similar, like this:

row

.container{
            display : flex;
    height : 100vh;
    flex-direction: row;
}

We can define flex-direction as either row or column. on the website when you use display: flex; by default direction will be row.

flex-direction: row;

Similarly

flex-direction: row | row-reverse | column | column-reverse;

row-reverse

column | column-reverse

flex-wrap

By default, flex items will all try to fit onto one line. You can change that and allow the items to wrap as needed with this property.

.container {
  flex-wrap: nowrap | wrap | wrap-reverse;
}

nowrap (default): all flex items will be on one line

wrap: flex items will wrap onto multiple lines, from top to bottom.

wrap-reverse: flex items will wrap onto multiple lines from bottom to top.

justify-content

This defines the alignment along the main axis. It helps distribute extra free space leftover when either all the flex items on a line are inflexible, or are flexible but have reached their maximum size. It also exerts some control over the alignment of items when they overflow the line.

.container {
  justify-content: flex-start | flex-end | center | space-between | space-around | space-evenly;
}

Other list of justify-content are below

flex-start (default): items are packed toward the start of the flex-direction.

flex-end: items are packed toward the end of the flex-direction.

start: items are packed toward the start of the writing-mode direction.

end: items are packed toward the end of the writing-mode direction. - left: items are packed toward left edge of the container, unless that doesn’t make sense with the flex-direction, then it behaves like start.

right: items are packed toward right edge of the container, unless that doesn’t make sense with the flex-direction, then it behaves like start.

center: items are centered along the line

space-between: items are evenly distributed in the line; first item is on the start line, last item on the end line

space-around: items are evenly distributed in the line with equal space around them. Note that visually the spaces aren’t equal, since all the items have equal space on both sides. The first item will have one unit of space against the

align-items

This defines the default behavior for how flex items are laid out along the cross axis on the current line. Think of it as the justify-content version for the cross-axis (perpendicular to the main-axis).

.container {
  align-items: stretch | flex-start | flex-end | center | baseline;
}

stretch (default): stretch to fill the container (still respect min-width/max-width)

flex-start / start / self-start: items are placed at the start of the cross axis. The difference between these is subtle, and is about respecting the flex-direction rules or the writing-mode rules.

flex-end / end / self-end: items are placed at the end of the cross axis. The difference again is subtle and is about respecting flex-direction rules vs. writing-mode rules.

center: items are centered in the cross-axis

baseline: items are aligned such as their baselines align
