Bootstrap 4 Badges
In this chapter you will learn Bootstrap 4 Badges. Globaltuts.com uses a simple lesson flow: explain the idea, show a working example, then highlight what to practice next.
This chapter is part of a longer track. Take your time, run every example locally, and use the Next link at the bottom when you are ready to continue.
What you will learn
- Define Bootstrap 4 Badges in plain language and know when to use it
- See how Bootstrap 4 Badges fits into legacy Bootstrap 4 interfaces
- Study a complete example with expected output
- Avoid common beginner mistakes called out in this lesson
- Complete the practice checklist before moving to the next chapter
Before you start
Bootstrap 4 examples assume jQuery and Bootstrap 4 CSS/JS are loaded.
You do not need to memorize everything on the first pass. Focus on running the example and noticing how it fits into the bigger picture of legacy Bootstrap 4 interfaces.
Common mistakes to avoid
- Changing many lines at once so you cannot tell which change fixed or broke the output.
- Deploying tutorial snippets to production without validation, authentication, or security review.
- Ignoring error messages; the first line of a stack trace usually points to the real problem.
- Skipping the example and only reading the headings—typing code yourself catches gaps in understanding.
Practice checklist
- Read the introduction once without typing, then read it again while following along.
- Run the example exactly as shown and confirm the output matches the preview.
- Change one variable or attribute and predict the result before refreshing.
- Write a two-sentence summary of Bootstrap 4 Badges in your own words in a notes file.
Introduction
Bootstrap 4 Badges is used when you work with legacy Bootstrap 4 interfaces.
If you are new, do not rush. Re-read this section, then type the example manually instead of copy-pasting blindly.
Keep official docs open in another tab; matching names to the manual beats memorizing syntax.
Concept in depth
When you see Bootstrap 4 Badges in documentation or on the job, it usually solves a specific problem: keeping legacy Bootstrap 4 interfaces predictable, maintainable, and easy for others to read.
Compare the example below with the previous chapter in this track. Notice what changed and ask yourself why the author structured it that way.
Example
The sample below is intentionally small so you can see the core idea. Extend it only after you understand each line.
Match your output to the preview under the code block. If something differs, check typos, file paths, and whether you saved the file.
<link href="https://cdn.jsdelivr.net/npm/bootstrap@4.6.2/dist/css/bootstrap.min.css" rel="stylesheet">
<div class="container py-3"><button class="btn btn-primary">Inbox <span class="badge badge-light">4</span></button></div>
Below is how the output typically looks in a browser, terminal, or API client:
Explanation
Open the previous lesson in this track and note what changed between the two examples.
Write a short note in your own words after each example so you remember why each line matters when you come back to this topic later.
