Thesun.co.uk Desktop Performance: 26/100
Quick overview:
Opportunities
These suggestions can help your page load faster. They don't directly affect the Performance score.
Remove unused CSS. Potential savings of 364 KiB

Use video formats for animated content. Potential savings of 1,565 KiB
Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes. Learn more
Remove unused JavaScript. Potential savings of 956 KiB
Remove unused JavaScript to reduce bytes consumed by network activity. Learn more.
Eliminate render-blocking resources. Potential savings of 880 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn more.
Avoid multiple page redirects. Potential savings of 340 ms
Redirects introduce additional delays before the page can be loaded. Learn more.
Properly size images. Potential savings of 221 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.
Enable text compression. Potential savings of 102 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Avoid an excessive DOM size
5,203 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn more.
Avoid `document.write()`
For users on slow connections, external scripts dynamically injected via `document.write()` can delay page load by tens of seconds. Learn more.
Ensure text remains visible during webfont load
Leverage the font-display CSS feature to ensure text is user-visible while webfonts are loading. Learn more.
Does not use passive listeners to improve scrolling performance
Consider marking your touch and wheel event listeners as `passive` to improve your page's scroll performance. Learn more.
Reduce the impact of third-party code
Third-party code blocked the main thread for 520 ms
Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading. Learn more.
Serve static assets with an efficient cache policy
113 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Avoid enormous network payloads
Total size was 6,730 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn more.
Minimize main-thread work
7.5 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn more
Reduce JavaScript execution time
3.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn more.
Avoid long main-thread tasks
13 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay. Learn more
User Timing marks and measures
6 user timings
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences. Learn more.
Keep request counts low and transfer sizes small
587 requests • 6,730 KiB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.
Avoid chaining critical requests
16 chains found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load. Learn more.
Avoid large layout shifts

These DOM elements contribute most to the CLS of the page.
Largest Contentful Paint element
1 element found
This is the largest contentful element painted within the viewport. Learn More

4 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers. Learn more.
Does not use HTTPS
1 insecure request found

This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being servedover HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs. Learn more.
Links to cross-origin destinations are unsafe
Add `rel="noopener"` or `rel="noreferrer"` to any external links to improve performance and prevent security vulnerabilities. Learn more.
User Experience
Displays images with incorrect aspect ratio
Image display dimensions should match natural aspect ratio. Learn more.
General
Uses deprecated APIs
1 warning found

Current page does not respond with a 200 when offline
If you're building a Progressive Web App, consider using a service worker so that your app can work offline. Learn more.
Installable
Does not register a service worker that controls page and `start_url`
The service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to homescreen, and push notifications. Learn more.
Does not use HTTPS
1 insecure request found
All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being servedover HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs. Learn more.
Web app manifest does not meet the installability requirements
Browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement. Learn more. Failures: No manifest was fetched.
Thesun.co.uk Desktop Accessibility: 64/100
Quick overview:
Contrast
These are opportunities to improve the legibility of your content.

Image elements do not have `[alt]` attributes
Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more.
Links do not have a discernible name
Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users. Learn more.
`<frame>` or `<iframe>` elements do not have a title
Screen reader users rely on frame titles to describe the contents of frames. Learn more.
Form elements do not have associated labels
Labels ensure that form controls are announced properly by assistive technologies, like screen readers. Learn more.
Best practices
These items highlight common accessibility best practices.
`[user-scalable="no"]` is used in the `<meta name="viewport">` element or the `[maximum-scale]` attribute is less than 5.
Disabling zooming is problematic for users with low vision who rely on screen magnification to properly see the contents of a web page. Learn more.
