# Flexbox No Wrap Explained (Example)

You need to master both Flexbox and CSS Grid in order to professionally build modern websites & web apps. If you haven't mastered both of them yet, I highly recommend going through my [CSS Course](https://bytegrad.com/courses/professional-css?utm_source=blog-post&utm_medium=blog-post&utm_campaign=blog-post).

Using Flexbox with a few flex-items is straightforward:

But now let's say you have many flex-items or very large flex-items that don't really fit on the same line, what happens? Well, they will flow outside the flex-container:

This is because the default is `flex-wrap: nowrap`.

I actually don't know why this is the default value, I think most of the time you want them to wrap onto a new line:

Simply use `flex-wrap: wrap` to achieve this.

By the way, I think CSS is the 'bottleneck' to most websites & web apps. I believe it's the highest-ROI skill you can master.

Before I mastered CSS, I lost a ton of time & energy fiddling around with CSS.

I was learning about advanced JavaScript topics when I couldn't even implement basic layouts in CSS...

So I created a CSS course to help you avoid the same mistake. Check it out [here](https://bytegrad.com/courses/professional-css?utm_source=blog-post-2&utm_medium=blog-post-2&utm_campaign=blog-post-2) if you're interested.
