Justify Text Bootstrap With Code Examples

As a full-stack developer and professional coder, effective text alignment is an important yet often overlooked aspect of clean web design. The right alignment can greatly improve readability, visual hierarchy, and polish on modern responsive web pages.

One of the most interesting text alignment options is text justification, where text is aligned along both the left and right edges of the content container. But text justification also comes with some unique considerations compared to left, right, or center text alignment.

In this comprehensive guide, we’ll explore justifying text with Bootstrap using the .text-justify utility class.

We’ll cover:

• How text justification works in web design
• The pros and cons of justified text
• Examples of justified text in web contexts like blogs and pricing tables
• Using Bootstrap’s `.text-justify` class for quick text justification
• Advanced justified layouts with CSS Flexbox and Grid
• Cross-browser compatibility and considerations
• Best practices for readable and accessible justified text

Whether you’re a Bootstrap beginner or a seasoned full-stack developer, this guide aims to cover text justification extensively including both code implementation as well as best practice considerations. Let’s dive in!

How Text Justification Works

Before we look specifically at justifying text with Bootstrap, let’s briefly understand how text justification works under the hood.

On the web, text is displayed within an element that can be thought of as a content container, such as a div, p tag or heading element. This content container displays according to the CSS box model:

By default, text starts aligning from the left border of the content container and wraps until it hits the right edge, continuing on the next line. This is termed left-aligned text.

But we can change this default behavior by altering the CSS text-align property:

text-align: right;   /* Right align text*/
text-align: center; /* Center text */ 
text-align: justify; /* Justify text */

The justify value is what aligns text both left and right by dynamically adding spacing between words to force the text to reach both edges.

This distributes the text evenly and creates a very uniform, almost magazine or print aesthetic.

Let‘s visualize some examples of different text alignment options:

Hopefully this gives some intuition for how Bootstrap‘s .text-justify class works under the hood.

Now, text justification may seem like an ideal alignment option. But there are also some downsides with justification to consider…

The Pros and Cons of Justified Text

Some benefits of justified text include:

• Uniform, print-like appearance
• Can improve perceived readability when executed well by defining clear vertical lines
• Provides strong visual consistency and polish when used judiciously, hence why it’s popular for marking some premium or exclusive typography-focused sections

However, some drawbacks also exist:

• Poorly adjusted word spacing can make justified text awkward to read or appear too “loose”
• Justification often works best for narrow column widths, but line lengths that are too long can strain readability
• Readability issues are further pronounced on mobile screens with even narrower widths
• More chance of uneven “rivers of white space” appearing within paragraphs

Later in this article we’ll share some best practices to counter these issues when using justified text. But first, let’s look at some examples of how justification is commonly used in web design.

Examples of Justified Text Alignment in Web Design

Some contexts where justified text works extremely well include:

Blog and Article Body Text

Online blogs and articles columns, much like newspapers and magazines, are prime candidates for justified text:

The narrow-to-medium column widths suit text justification, allowing the vertical flow to shine.

Pricing or Comparison Tables

For premium pricing components like tables, text justification can further emphasize special treatment:

Just make sure to keep columns narrow to retain readability.

Exclusive / Premium Callout Sections

Need a stylized section to indicate premium offerings or special limited-time exclusives? Justified copy communicates specialty and polish:

When used sparingly, justification guides the eye marvelously.

Now that we’ve seen some examples out in the wild, let’s look at the mechanics…

Justifying Text using Bootstrap’s .text-justify Utility

Bootstrap makes it super easy to start justifying text on our web pages with the .text-justify utility class:

<p class="text-justify">This entire paragraph will now be fully justified.</p>

Let’s break down what’s happening:

• We add `.text-justify` to any block-level text container like p, div, headings etc
• Behind the scenes, this applies text-align: justify; to the element
• This CSS rule forces text to spread edge-to-edge horizontally

And we can stack additional utilities for further styling customization:

<p class="text-justify text-lg font-serif px-4">A nice roomy justified paragraph!</p> 

What if we only wanted to justify part of a paragraph or text block instead of the whole thing?

Bootstrap‘s utilities can handle that as well:

<p>
  Lorem ipsum dolor sit amet consectetur adipisicing elit. 
  <span class="text-justify">This inner portion is justified within the regular text.</span>
  Quisquam dignissimos delectus cumque porro...
</p>

The flexibility here is wonderful!

Now that we’re comfortable with the basics, let’s move on to…

Advanced Justified Layouts with CSS Flex & Grid

Bootstrap jumpstarts simple justification, but modern CSS also unlocks more advanced justified layout building blocks without needing custom classes.

For example, Flexbox and CSS Grid allow us to construct entire page sections with justified and centered text simultaneously:

Justified Flex Container

.flex-section {
  display: flex; 
  flex-direction: column;
  justify-content: center;
  text-align: justify;
}

The justify-content and text-align properties will align the text both vertically centered and horizontally justified.

We can do the same with Grid:

Justified Grid Container

.grid {

  display: grid;
  align-content: center;
  text-align: justify;

}

This allows full sections like hero banners to utilize justification while keeping responsive mobile-friendliness:

So much design awesomeness packed into simple layout primitives!

Okay, we have some flashy justified text now…but how useable and accessible is it? Let‘s find out…

Cross Browser Compatibility and Considerations

Text justification works excellently across modern browsers supporting flexbox and grid.

Internet Explorer has no issues either provided we have a defined width for the text container (as text flows less predictably in undefined column spaces).

The main consideration for cross-browser compatibility is spacing. Part of justifying text means intelligently stretching whitespace and word spacing evenly.

Older browsers like pre-Chromium Edge handle these spacing calculations differently. The text may end up looking very “loose” and have wide rivers of gaping white space:

Fortunately this is less of a concern in 2021 with most traffic on modern Chrome, Firefox, Safari and Chromium Edge. But for maximal compatibility…

Enforce Optimal Line Length

By capping line length, worst-case spacing will damage readability less:

max-width: 45em; 

Allow Non-Justified Fallback

Alternatively, we can default back to regular left-aligned text on older browsers with:

text-align: justify;  
text-align-last: left;

The text will justification modern browsers, but left align within paragraphs on older ones.

Both methods allow our fancy justified layouts to degrade gracefully!

Now that we‘re compatible everywhere…how do we optimize these designs for on-page usability?

Best Practices for Readable & Accessible Justified Text

Like any technique, text justification gives the best results when used mindfully and in moderation.

Here are some key best practices:

Limit Line Length

Keep maximum line length between 45-90 characters:

max-width: 45em;

Wider lengths strain reading comfort when combined with altered word spacing.

Use Larger Font Sizes

Boost text to at least 16px+ to improve spacial recognition:

font-size: 1.15rem; 

Increase Letter Spacing Slightly

Subtly more spacing creates cleaner definition:

letter-spacing: 0.5px;

Left Align Numerical Data Tables

Tables containing more sensitive numerical data or comparisons should left align instead:

.data-table {
  text-align: left;
}

Limit Adjacent Justified Elements

To avoid compounding issues with spacing, avoid using justification liberally everywhere. Use it purposefully to match tone.

Putting it All Together as a Full-Stack Developer

Hopefully this guide has taken your Bootstrap text alignment skills to the next level!

We looked holistically at both justification implementations as well as typography-focused best practices.

Some key takeaways as a full-stack developer:

• Use `.text-justify` for easy justification with Bootstrap‘s utilities
• Leverage Flexbox and Grid for robust responsive justification
• Mind both browser compatibility and on-page usability
• Apply justification judiciously based on context

Our overall goal remains enhancing design while keeping user comfort core to all layout decisions – text alignment included!
