CSS Basic: text-combine-upright

CSS (Cascading Style Sheets) is a powerful tool that allows web developers to control the appearance and layout of their web pages. One of the lesser-known CSS properties is text-combine-upright, which can be used to combine multiple characters into a single vertical glyph. In this article, we will explore the basics of text-combine-upright and its potential applications.

Understanding text-combine-upright

The text-combine-upright property is used to control the rendering of East Asian characters, such as Chinese, Japanese, and Korean, when they are displayed vertically. By default, these characters are displayed individually, but with text-combine-upright, they can be combined into a single glyph.

When using text-combine-upright, the characters are stacked vertically, with the first character at the top and subsequent characters below it. This can be particularly useful when dealing with long strings of characters, as it helps to save space and improve readability.

Using text-combine-upright

To use text-combine-upright, you need to apply it to the CSS selector that targets the text you want to combine. For example:

.vertical-text {
  text-combine-upright: all;
}

In the above example, the text-combine-upright property is applied to the .vertical-text class, which means that any text within an element with this class will be displayed vertically and combined into a single glyph.

It's important to note that text-combine-upright is not supported by all browsers, so it's essential to test your code across different browsers to ensure consistent rendering. Additionally, it's worth mentioning that this property only applies to East Asian characters and may not have any effect on other languages.

Examples

Let's take a look at a couple of examples to see how text-combine-upright can be used:

<div class="vertical-text">
  你好世界
</div>

In the above example, the characters "你好世界" will be displayed vertically and combined into a single glyph.

<div class="vertical-text">
  こんにちは
</div>

In this example, the characters "こんにちは" will be displayed vertically and combined into a single glyph.

Conclusion

The text-combine-upright property is a useful tool for controlling the rendering of East Asian characters when displayed vertically. By combining multiple characters into a single glyph, it can help save space and improve readability. However, it's important to remember that this property is not supported by all browsers and only applies to East Asian characters. So, if you're working with East Asian text and want to experiment with vertical display, give text-combine-upright a try!
