# Improve Page Speed by Moving Large Inline CSS to an External File

CSS Analyzer

## What is this warning?

Your page has a very large chunk of CSS code embedded directly in the HTML. This is called an 'inline stylesheet.' While it works, it makes your HTML file bigger and slower to download. Moving this code to a separate file allows browsers to save a copy of it, making other pages on your site load faster.

## How to Fix This Issue

### How to Fix It

#### The Problem

A `<style>` block in your HTML with hundreds of lines of CSS.

#### The Solution

1. Cut the CSS code from your HTML file. 2. Paste it into a new file (e.g., `main.css`). 3. Link to this new file from your HTML.

```
<!-- Remove the large <style> block and replace it with this -->
<link rel="stylesheet" href="/css/main.css">
```

#### Why This Works

External stylesheets can be 'cached' by the browser. This means after the first visit, the browser doesn't have to download the CSS file again, making subsequent page loads much quicker. This improves performance and user experience.

### SEO Impact

This issue can affect your site's search engine rankings and user experience. Addressing it promptly helps ensure optimal performance and visibility in search results.
