HTML, CSS, and Web Development Practices: Past, Present, and Future

Post from October 15, 2009 (↻ September 27, 2020), filed under .

This and many other posts are also available as a pretty, well-behaved ebook: On Web Development.

This post is partially outdated.

The following is the more detailed alternative version of today’s talk at Teaching the Web, Potsdam. While blog posts occasionally get updated, this one might not.

The Ideal World

Web development practices, the ideal situation.

Figure: Shiny, maintainable web development world. Structure, presentation, and behavior all separated except for some minor overlap with respect to integration (style sheet references in HTML documents, for instance) and interfaces (scripts manipulating documents in a smart manner).

The Past (1990-1999)


Development Practices

Web development practices in the past (around 1999).

Figure: Heaps of presentational markup taking care of what would be the job of style sheets; scripts manipulating document contents but also eyes, thus overlapping both structure and presentation.


The Present (2000-2009)


Development Practices

Web development practices in the present (2009).

Figure: Behavior moving over to manipulate more documents in an obtrusive fashion (also known as AJAX; pun intended); structure overlapping less presentation, as authors learn to use less presentational markup.


The Future (2010-2019)


Development Practices

Web development practices in the future (around 2019/2020).

Figure: Behavior backing off a bit, minding its own business a bit more; authors learning to separate even more structure, presentation, and behavior, without being quite there yet (aka “the ideal world”).


Priorities for Web Developers

Development Practices Compared

Web development practices, a comparison of the past, the present, the future, and the ideal situation we envision.

Figure: Bubbles all over the place; authors using less presentational markup and manipulating documents and styling-related aspects in a less wild fashion over time.

Many thanks to Asim Janjua for his work on the talk’s visuals.

    Nicely done Jens, a good read; must have been a great presentation. If you find yourself back in the Bay area any time soon, come and give the talk on campus. (Please)

    I believe web development is getting more and more advanced nowadays, and I think advancements always go for the good. It’s like the rushing water in pool fountains, no one can stop it from continuously flowing. However, we have also to regulate it, like make its pace slower coz only a few can keep up.

Cover: CSS Optimization Basics.

Perhaps my most relevant book: CSS Optimization Basics (2018). Writing CSS is a craft. As craftspeople we strive to write high quality CSS. In CSS Optimization Basics I lay out some of the most important aspects of such CSS. (Also available in a bundle with Upgrade Your HTML and The Web Development Glossary.)
