As more of our social and work lives move to the online world, it becomes even more important for people with disabilities to be able to participate in all online interactions without barriers. Just as building architects can create or omit accessibility features such as wheelchair ramps, web developers can help or hinder the assistive technology users rely on.

@@ -63,10 +63,10 @@ There are two ways of doing the compression on the server side:
   - Dynamically Compressed (compress assets on-the-fly after a request is made)
 
 Since precompression is done beforehand, we can spend more time compressing the assets. For dynamically compressed resources we need to choose the compression levels such that compression takes less time than time difference between sending an uncompressed versus a compressed file. Currently practically all text compression is done by one of two HTTP content encodings: [Gzip](https://tools.ietf.org/html/rfc1952) and [brotli](https://github.com/google/brotli). Both are widely supported by browsers: [can I use brotli](https://caniuse.com/?search=brotli)/[can I use gzip](https://caniuse.com/?search=gzip)
-When you want to use gzip, consider using [Zopfli](https://en.wikipedia.org/wiki/Zopfli), which generates smaller gzip compatible files. This should be done especially for precompressed resourses, since here the greatest [gains are expected](https://cran.r-project.org/web/packages/brotli/vignettes/brotli-2015-09-22.pdf) .

 As the HTTP protocol has evolved, the semantics of HTTP have stayed the same; there have been no changes to the HTTP methods (such as GET or POST), status codes (200, or the dreaded 404), URIs, or header fields. Where the HTTP protocol has changed, the differences have been the wire-encoding and the use of features of the underlying transport.
 
-HTTP/1.0, published in 1996, defined the text-based application protocol, allowing clients and servers to exchange messages in order to request resources. A new TCP connection was required for each request/response, which introduced overhead. TCP connections use a congestion control algorithm to maximise how much data can be in-flight. This process takes time for each new connection. This "slow-start" means that not all the available bandwidth is used immediately.

This process takes time for each new connection. This "slow-start" means that not all the available bandwidth is used immediately.
 
 In 1997, HTTP/1.1 was introduced to allow TCP connection reuse by adding "keep-alives", aimed at reducing the total cost of connection start-ups. Over time, increasing website performance expectations led to the need for concurrency of requests. HTTP/1.1 could only request another resource after the previous response had completed. Therefore, additional TCP connections had to be established, reducing the impact of the keep-alive connections and further increasing overhead.

 ## A not so distant future
 
 We have watched for 25 years page weight grow steadily. It might have been one of the greatest stock investments — had it been one. But this is the web. And, we are trying to manage data, requests, file size and ultimately page weight. We have just combed over data, seeing how images are the greatest source of weight. This means, it will also be our greatest source of savings. 2020 was a pivotal year, a possible inflection point for HTTP Archive tracking of web data. 2020 marked the year the modern format webp was finally adopted by Safari, making this format finally supported by all browsers across the board. This means that the format could comfortably be used with little to no fall back. The most important point? The potential for significant page weight savings is unavoidable — at a possible 30%. Even more interesting is the idea of a more modern format: avif. This format has burst onto the scene with enough support today for approximately 70% browser market share, creating a scenario for small image file sizes - even smaller than webp. And lastly, and possibly most distant: media queries level 5, ‘prefers-reduced-data ‘. Though in very early draft, this media feature will be used to detect if a user may have a preference for variant resources in data sensitive situations
