KaTeX is a fast, lightweight library for rendering mathematical expressions on web pages. Integrating KaTeX into your Blogger website enables you to display beautifully formatted mathematical equations and formulas. Below is a comprehensive guide to help you set up and use KaTeX in your Blogger posts.
Step 1: Include KaTeX Libraries
To render equations using KaTeX, you need to include the KaTeX CSS and JavaScript files in your Blogger template.
Log in to Blogger
Go to your Blogger dashboard and select the blog where you want to implement KaTeX.
Edit HTML Template
Navigate to
Theme>Customize>Edit HTML.
Add KaTeX Links
Paste the following lines inside the
<head>tag of your HTML template:
<!-- KaTeX Supports -->

<script>
document.addEventListener("DOMContentLoaded", function() {
renderMathInElement(document.body, {
delimiters: [
{left: '$$', right: '$$', display: true},
{left: '$', right: '$', display: false},
{left: '\\(', right: '\\)', display: false},
{left: '\\[', right: '\\]', display: true}
],
throwOnError: false
});
});
</script>

4.Save the changes to your template.
Step 3: Writing KaTeX in Posts
You can now include mathematical expressions in your blog posts using KaTeX.
Compose a Post
Go to the Blogger editor and write a new post.
Insert LaTeX Expressions
Write your math expressions using the appropriate delimiters:
For inline math, use
$...$(e.g.,$E = mc^2$).For block math, use
$$...$$(e.g.,$$\int_{a}^{b} f(x) dx$$).
Publish the Post
Preview the post to ensure the equations render correctly, then publish it.
