Load render-blocking scripts asynchronously Static HTML pages, like blog posts, can usually be cached without adverse effects. Use caution, because you don’t want to serve up an old version of a website. Caching rules allow you to dictate where users’ browsers will request the document from – the cache or the server. That being said, it is possible to cache HTML. CachingĬaching is not always used for HTML either, because HTML files tend to change frequently. While you can minify HTML if you wish to do so, it can make the document more difficult to read, especially if the page changes often. Minification deletes all unnecessary whitespace and all new line characters, and is not common practice in HTML. There are some kinds of optimizations done regularly to other files that are not standard for HTML. HTML Delivery Tip #3: Use non-standard optimizations as needed If you’re not compressing HTML and other files, your site is likely slower than competitors. Total compressed page size is about half as large in MB as the uncompressed page size. GZIP compression or a similar compression model allows less data to be sent to an end user’s browser to construct the same page. HTML Delivery Tip #2: Compress HTML server-side You can also use a tool like HTML Tidy to strip out whitespace and extra blank lines from valid HTML.

Mozilla recommends indenting with 2 spaces rather than a tab – the equivalent of 4 spaces – and only separating blocks of code with a blank line when there is a good reason. The script tag should be succinct and look something like this: Reduce blank lines and unnecessary indentation.
When a browser sees a tag in HTML, it also assumes JavaScript, so the type attribute does not need to be declared. Link directly to a JavaScript file instead. The type attribute does not need to be declared so that the reference to the external stylesheet looks something like this: Don't use inline scripts. Link to a stylesheet in the of the document instead of using inline styles. The ones that reduce the HTML file length most follow. HTML Delivery Tip #1: Clean up HTML so it is conciseįollowing W3C specifications for markup makes HTML more maintainable and readable. Compress the HTML file so that smaller file size is delivered.Clean up excess HTML code to shorten the file length.Reducing the size of the HTML file helps reach this goal, with two main ways to do so: Ideally, you would be able to include multiple files in that first connection, like CSS with server push, in order to complete the critical rendering path in a shorter amount of time. So if the HTML is larger than 14.3KB, it will take multiple roundtrips to deliver the base file. If the server receives confirmation from the client that it received the data, the server will double how much data it sends for each successive trip.ġ0 TCP packets is equivalent to about 14.3KB.The server waits for the client (i.e., browser) to acknowledge the data.On a new connection, the server can send up to 10 TCP packets in the first roundtrip.HTML gets delivered like any other file on the internet – over a network in data packets, which have limited room for data. Use non-standard optimizations as needed.I’m also going to explain why these optimizations are recommended, which will get a little technical, so I’ve included an overview at the beginning of each section, and then a TL DR at the end. Which syntactical pieces affect modern HTML parsing the most.

When HTML takes a long time to load, parse, and download external files, user experience can suffer. The power of HTML lies in its versatility, mainly because it can load other files – which is what hypertext, the first part of HTML, means. Without HTML, JavaScript wouldn’t be able to run, CSS wouldn’t be able to style anything, and images wouldn’t have a place to load. It is the document type that builds the structure of a website.
