Flexbox: A Complete Guide to justify-content: flex-start

If you're a front-end developer, you're probably familiar with flexbox. It's an essential part of CSS that allows us to create dynamic, responsive layouts. In this guide, we'll dive into one of the most common flexbox properties: justify-content: flex-start.

What is justify-content?

justify-content is a flexbox property that controls the horizontal alignment of flex items within a container. There are five possible values for justify-content:

1. flex-start
2. flex-end
3. center
4. space-between
5. space-around

In this guide, we'll focus on flex-start.

How does justify-content: flex-start work?

When you set justify-content: flex-start on a container element, the flex items will be aligned to the left side of the container. This is the default behavior of flexbox, so you don't actually need to specify justify-content: flex-start unless you want to override some other value.

Here's an example:

.container {
  display: flex;
  justify-content: flex-start;
}

In this example, the .container element is a flex container, and its children will be aligned to the left side of the container.

Other justify-content values

As mentioned earlier, there are four other possible values for justify-content. Here's a quick overview of each one:

• flex-end: Aligns items to the right side of the container.

• center: Centers items horizontally within the container.

• space-between: Distributes items evenly within the container, with the first item aligned to the left and the last item aligned to the right.

• space-around: Distributes items evenly within the container, with equal space between each item.

Conclusion

justify-content: flex-start is a simple but essential flexbox property that allows you to align flex items to the left side of a container. With the other possible values of justify-content, you can create a wide variety of flexible, responsive layouts.

Now that you know how justify-content: flex-start works, it's time to put it into action and start experimenting with other flexbox properties as well!
