When a browser renders plain HTML, it applies a very basic "user agent" stylesheet. This makes text readable, but it lacks personality and visual hierarchy. **CSS Typography** is the art of using CSS properties to style text, transforming it from a simple block of words into a powerful tool for communication, branding, and user experience.
In this article, we'll explore four of the most fundamental properties for controlling your text's layout, case, and spacing.
1. `text-align`: Controlling Horizontal Flow
The `text-align` property defines the horizontal alignment of text within its containing element. It's the first tool you'll reach for when positioning text.
left: The default value for left-to-right languages. Text is aligned to the left edge.right: Text is aligned to the right edge. Useful for figure captions or special design elements.center: Centers the text. This is most commonly used for headings, titles, and calls-to-action.justify: Stretches each line (except the last) so that they have equal width, creating clean edges on both the left and right sides. While common in print, **use `justify` with caution on the web**. It can create awkward, large gaps between words (called "rivers"), which can severely harm readability.
There are also newer, logical values like start and end, which align text based on the document's writing direction (e.g., `start` is `left` in English but `right` in Arabic).
2. `text-transform`: Changing Capitalization
This property allows you to control the capitalization of text without changing the underlying HTML. This is excellent for accessibility and maintenance, as a screen reader will still read the original, properly-cased text.
uppercase: Transforms all characters to uppercase (ALL CAPS). Ideal for strong, impactful headings.lowercase: Transforms all characters to lowercase.capitalize: Capitalizes the first letter of each word. Useful for subheadings or navigation items.none: The default. No transformation is applied.
3. `letter-spacing`: The Space Between Characters
Known as **"tracking"** in graphic design, `letter-spacing` adjusts the space between individual characters. It can have a dramatic effect on readability and style.
You can provide a length value (like px, em, or rem).
- Positive values (e.g.,
2px) spread letters apart, creating an airy, elegant, or emphatic feel. This is often applied to uppercase headings. - Negative values (e.g.,
-0.5px) pull letters closer together. This "tighter" tracking is often used in large display fonts to improve visual balance.
4. `line-height`: The Space Between Lines
Known as **"leading"** in print design, `line-height` controls the vertical space between lines of text. This is arguably the most important property for the readability of long-form text.
While you *can* use units like px or em, the **best practice** is to use a **unitless number**:
✔️ Good Practice
p {
font-size: 16px;
line-height: 1.6;
}The line height will be 1.6 * 16px = 25.6px. This ratio is inherited by child elements, so it always scales correctly.
❌ Bad Practice
p {
font-size: 16px;
line-height: 26px;
}A fixed `26px` height is inherited. If a child element has a larger font size, its text will overlap, breaking the layout.
For body text, a `line-height` between `1.5` and `1.8` is generally recommended for optimal readability.
Key Takeaway: Combine these properties to create a clear visual hierarchy. Use `text-align` and `text-transform` for headings. Use `line-height` for readable paragraphs. Use `letter-spacing` to add a final touch of polish.
