When was flex introduced

The display from the to syntax changed from box to flexbox. The version of the Flexbox spec is in W3C candidate recommendation. This means the spec is stable, supported in browsers, tests are being written for it and there should not be a significant change from this version. Again, the syntax is edited from its previous version and Opera releases un-prefixed support. To start to use Flexbox, all you need to do is create a flex container using the display: flex property.

After that, every element that you have inside that flex container turns into a flex item. We can change the direction of our flex items in our flex container very easily to a column, by passing a flex-direction: column property to our flex container.

Flexbox has a lot of other properties that we can use to create awesome things. We can order the elements the way we want, we can reverse the order of elements, we can determine if our elements should grow or shrink, etc. We can easily reverse the order of an element using the order property.

If we wanted to change the order of the element with id of two , we would do this:. Now our element is the last one in the flex container.

To define a grid container, all you need to do is pass a display: grid property to your block element. Now you have a grid, so you should define how many rows and columns do you want.

To create rows you use the grid-template-rows property, and pass how many you want, like this:. Flexbox helped developers start to create more responsive and maintainable web applications, but the main idea of a one-dimensional layout system does not make sense when you need to build a more complex layout design.

CSS grid really came to help us build more complex layout designs using a two-dimensional way, using both rows and columns. We should aim to use both of them together, but for different purposes. For your layout, use CSS grid, for alignment of your elements, use Flexbox. Flex » Company » Our story ».

You can always refer back to it if you get confused about any of the terms being used. Flexbox provides a property called flex-direction that specifies which direction the main axis runs which direction the flexbox children are laid out in.

By default this is set to row , which causes them to be laid out in a row in the direction your browser's default language works in left to right, in the case of an English browser. You'll see that this puts the items back in a column layout, much like they were before we added any CSS. Before you move on, delete this declaration from your example. Note: You can also lay out flex items in a reverse direction using the row-reverse and column-reverse values. Experiment with these values too!

One issue that arises when you have a fixed width or height in your layout is that eventually your flexbox children will overflow their container, breaking the layout. Have a look at our flexbox-wrap0. Here we see that the children are indeed breaking out of their container. We now have multiple rows.

Each row has as many flexbox children fitted into it as is sensible. Any overflow is moved down to the next line. The flex: px declaration set on the articles means that each will be at least px wide.

We'll discuss this property in more detail later on. You might also notice that the last few children on the last row are each made wider so that the entire row is still filled. But there's more we can do here. First of all, try changing your flex-direction property value to row-reverse. Now you'll see that you still have your multiple row layout, but it starts from the opposite corner of the browser window and flows in reverse.

At this point it's worth noting that a shorthand exists for flex-direction and flex-wrap : flex-flow. So, for example, you can replace. Let's now return to our first example and look at how we can control what proportion of space flex items take up compared to the other flex items.

Fire up your local copy of flexbox0. This is a unitless proportion value that dictates how much available space along the main axis each flex item will take up compared to other flex items. This value is proportionally shared among the flex items: giving each flex item a value of would have exactly the same effect.

You can also specify a minimum size value within the flex value. Try updating your existing article rules like so:.
