Recently, while editing some CSS in Opera inspector, I noticed a CSS property called writing-mode, that was the first time I knew of it. After some research, I learned that its purpose is for vertical language scripts, like Chinese or Japanese. However, the interesting thing is that when using it with English, we can create a vertical text very easily.

The writing-mode property defines whether lines of text are laid out horizontally or vertically and the direction in which blocks progress. As of MDN

The default writing mode

Browser agents that support this propery will have horizontal-tb as the default value. This works for horizontal language scripts like: English, French, Arabic.. etc

We will explore the value of vertical-lr, lr stands for (Left to right).

Example 1

In the above design, we have a section title that is rotated 90deg around the top left of it’s origin. If you want to do this without CSS writing-mode, we need to do the following:

1. Create a positioning context for the wrapper element by adding position:relative.
2. Position the title absolutely by adding position: absolute.
3. Change the transform origin based on how we want to rotate it. In our case we want to change it to the top left corner, so we add transform-origin: left top.
4. Rotate the title by adding transform: rotate(90deg).
5. Finally, we need to add some padding on the left side of the wrapper element in order to prevent the overlap between the section title and grid items.

{% highlight html %}

{% endhighlight %}

{% highlight css %} .wrapper { position: relative; padding-left: 70px; }

.section-title { position: absolute; left: 0; transform-origin: left top; transform: rotate(90deg); } {% endhighlight %}

A lot of work to do for such design, right? Lets explore how this could be done using CSS writing-mode:

{% highlight css %} .section-title { writing-mode: vertical-lr; } {% endhighlight %}

We’re done! :D As you see, there is no need to position anything or add padding as we did. Checkout the demo below:

Example 2

With the above design, we have a sharing widget that is placed vertically beside the content. It’s true that we can make this easily without CSS writing-mode, but the interseting thing is that when using it with the social widget, we will get the ability to vertically center it (left, center or right).

As in the example, the social widget is vertically aligned to the top of its parent. By changing CSS text-align propery, we can change the position of it. For example:

{% highlight css %} .social-widget { writing-mode: vertical-lr; text-align: right; } {% endhighlight %}

This will align it to the bottom of it’s parent! Easy, right? In the next example, it will be centered vertically.

{% highlight css %} .social-widget { writing-mode: vertical-lr; text-align: center; } {% endhighlight %}

And here is the demo for the social widget:

Disclaimer: I stopped using icon fonts and switched to SVG, I’m using the icon fonts for the sake of the demo only.

Browsers Support

The global support is 84.65% and this is really good. You can use the property today in order to get benefit like we did in our examples.

Look at that green! :)
