Master Text Alignment with CSS: Complete Guide to Elegant Designs

Mastering text alignment in CSS is a must-have skill for any web designer or developer. Well-aligned text not only improves readability and accessibility, but also contributes to the overall design aesthetic, offering a cohesive and professional user experience. In the following tour, we are going to break down the techniques and properties that will allow you to align text effectively, ensuring that your web projects stand out for their quality and visual precision.

Text Alignment Properties in CSS

When we talk about text alignment, the first thing we need to consider are the basic CSS properties that allow us to control how our textual content is laid out within an HTML element. The properties text-align, vertical-align, and line-height are essential in this sense.

Text-Align: Horizontal Alignment

text-align is the best known property for horizontal alignment and offers several options:

• left: Aligns the text to the left of the container.
• right: Aligns the text to the right.
• center: Centers the text horizontally.
• justify: Arranges the text so that the lines fill the entire width of the container.

Example:

p { text-align: center; }

Vertical-Align: Vertical Alignment

The property vertical-align It is mainly used in inline or table elements to align text vertically. Does not affect block elements such as div o p. Some common values are:

• baseline: The default value, aligns the text by its baseline.
• middle: Centers the text vertically.
• top: Aligns the text with the top of the highest element in the line.
• bottom: Aligns the text with the bottom of the lowest element in the line.

Example:

img { vertical-align: middle; }

Line-Height: Line Height

The property line-height It is crucial to control the vertical space between lines of text. It is a great ally to improve the readability and visual appearance of the text.

Example:

p { line-height: 1.6; }

The unit can be a number (relative to the current font size), a value in pixels, em, rem, or percentage.

Flexbox and Text Alignment

Flexbox is a modern design model that provides more sophisticated control over the alignment of text and other elements within a container. Through display: flex;, we can use additional properties like justify-content y align-items to align the text horizontally and vertically, respectively.

Justify-Content: Horizontal Alignment in Flexbox

With Flexbox, justify-content offers more horizontal alignment options than text-align:

• flex-start: Aligns the elements to the start of the container (left).
• flex-end: Aligns the elements to the end (right).
• center: Centers the elements.
• space-between: Arranges the elements so that the first element is at the beginning and the last element is at the end, with equal spacing between the elements.
• space-around: Distributes space around elements evenly.
• space-evenly: Distributes space between and around elements evenly.

.container { display: flex; justify-content: center; }

Align-Items: Vertical Alignment in Flexbox

To control the vertical alignment in a Flexbox container, we use align-items:

• stretch: Stretch the items to fill the container.
• flex-start: Aligns the elements on top of the container.
• flex-end: Aligns the elements at the bottom of the container.
• center: Aligns the elements in the center vertically.
• baseline: Aligns elements on the text baseline.

.container { display: flex; align-items: center; }

Aligning Text with CSS Grid

Another powerful tool for text alignment is CSS Grid Layout. Similar to Flexbox, but more suitable for two-dimensional designs.

Justify-Items and Align-Items in CSS Grid

CSS Grid provides the properties justify-items to align elements horizontally and align-items to align vertically within grid cells.

.container { display: grid; justify-items: center; align-items: center; }

With these properties, you can control the alignment of the content within each grid cell, not just the text.

Text Alignment with Positioning

Sometimes it is necessary to use positioning techniques to align text, especially when other methods do not provide the necessary control.

Absolute Positioning

Absolute positioning allows you to move elements outside the normal flow of the document and position them precisely.

.text { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); }

With this technique, we can center a textual element both horizontally and vertically.

Good Practices and Final Considerations

Aligning text with CSS may seem simple, but it requires attention to detail and practice to avoid accessibility and responsiveness issues. Some recommendations are:

• Use relative units: Like em, rem, or percentages for better adaptability.
• Test with multiple browsers: Make sure your text aligns correctly in all popular browsers.
• Consider readability: Don't sacrifice readability for style. Make sure your text is easy to read on different devices.
