Avoids an excessive DOM size - 599 elements
Browser engineers recommend pages contain fewer than ~1,500 DOM elements. The sweet spot is a tree depth < 32 elements and fewer than 60 children/parent element. A large DOM can increase memory usage, cause longer [style calculations](https://developers.google.com/web/fundamentals/performance/rendering/reduce-the-scope-and-complexity-of-style-calculations), and produce costly [layout reflows](https://developers.google.com/speed/articles/reflow).

Preconnect to required origins
Consider adding preconnect or dns-prefetch resource hints to establish early connections to important third-party origins. Learn more.

Minify CSS
Minifying CSS files can reduce network payload sizes. Learn more.

Server Backend Latencies - 0 ms
Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance. Learn more.

Minimize Critical Requests Depth - 10 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.

Preload key requests
Consider using to prioritize fetching resources that are currently requested later in page load. Learn more.

Minify JavaScript
Minifying JavaScript files can reduce payload sizes and script parse time. Learn more.

User Timing marks and measures
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences. Learn more.

Use video formats for animated content
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.

Server response times are low (TTFB) - Root document took 580 ms
Time To First Byte identifies the time at which your server sends a response. Learn more.

Enable text compression
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more.

Network Round Trip Times - 0 ms
Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance. Learn more.

Avoids an excessive DOM size - 599 elements
Browser engineers recommend pages contain fewer than ~1,500 DOM elements. The sweet spot is a tree depth < 32 elements and fewer than 60 children/parent element. A large DOM can increase memory usage, cause longer [style calculations](https://developers.google.com/web/fundamentals/performance/rendering/reduce-the-scope-and-complexity-of-style-calculations), and produce costly [layout reflows](https://developers.google.com/speed/articles/reflow).

Suggestions Summary

Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 1 blocking script resources and 2 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.Remove render-blocking JavaScript:

https://stijl.kuleuven.be/2016tmp/js/modernizr.min.js
Optimize CSS Delivery of the following:

https://fonts.googleapis.com/css?family=Material+Icons|Open+Sans:400italic,600italic,700italic,400,700,600|Merriweather:400italic,400,700
https://stijl.kuleuven.be/2016tmp/css/main.min.css

Optimize images

Properly formatting and compressing images can save many bytes of data.

Optimize the following images to reduce their size by 277.5KiB (33% reduction).

Compressing https://www.kuleuven.be/kuleuven/img/nieuws-start-academiejaar.jpg could save 170.2KiB (48% reduction).
Compressing https://www.kuleuven.be/kuleuven/img/homepagina-opening-academiejaar2019.jpg could save 61.3KiB (15% reduction).
Compressing https://www.kuleuven.be/kuleuven/img/nieuws-hersengebied.jpeg could save 46.1KiB (59% reduction).

Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Leverage browser caching for the following cacheable resources:

https://stijl.kuleuven.be/2016tmp/css/main.min.css (expiration not specified)
https://stijl.kuleuven.be/2016tmp/img/sedes-kuleuven.png (expiration not specified)

https://connect.facebook.net/signals/plugins/inferredEvents.js?v=2.9.4 (20 minutes)
https://www.google-***ytics.com/***ytics.js (2 hours)

Avoid landing page redirects

Your page has 2 redirects. Redirects introduce additional delays before the page can be loaded.

Avoid landing page redirects for the following chain of redirected URLs.

http://kuleuven.be/
https://www.kuleuven.be/
https://www.kuleuven.be/kuleuven/

Minify HTML

Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and p*** times.

Minify HTML for the following resources to reduce their size by 1.8KiB (20% reduction).

Minifying https://www.kuleuven.be/kuleuven/ could save 1.8KiB (20% reduction) after compression.

Size tap targets appropriately

Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.

The following tap targets are close to other nearby tap targets and may need additional spacing around them.

The tap target <a href="http://www.kul….be/onderzoek/">Onderzoek</a> and 2 others are close to other tap targets.
The tap target <a href="http://www.kul….be/onderzoek/">Onderzoek</a> and 2 others are close to other tap targets.
The tap target <a href="#">Interne tools </a> and 3 others are close to other tap targets.

Enable compression

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.

Enable compression for the following resources to reduce their transfer size by 462B (49% reduction).

Compressing https://stijl.kuleuven.be/2016tmp/img/svg/logo.svg could save 462B (49% reduction).
Avoid plugins
Your page does not appear to use plugins, which would prevent content from being usable on many platforms. Learn more about the importance of avoiding plugins.
Configure the viewport
Your page specifies a viewport matching the device's size, which allows it to render properly on all devices. Learn more about configuring viewports.
Reduce server response time
Your server responded quickly. Learn more about server response time optimization.
Minify CSS
