Jeremy Wagner’s “Now THAT’S What I Call Service Worker!” provides innovative techniques to harness the power of Progressive Web Apps with smaller HTML payloads and better performance for repeat visitors.
In a special double issue of A List Apart, for people who make websites, Shelley Powers takes a second look at SVG and likes what she sees. You may, too.
Many of us think of Scalable Vector Graphics (SVG) as an also-ran: fine for charts and tables, but not much else. Yet SVG can actually enhance a site’s overall design, and can be made to work in even the most stubborn browser.
In Part I, Shelley covers important basics of working with SVG, including browser support and accessibility.
In Part II, dig deeper into the technology behind using SVG for your site design. Explore how to incorporate SVG in a cross-browser friendly manner, including using SVGWeb to ensure that the SVG shows in Internet Explorer. And discover the unique characteristic that makes SVG ideal for page backgrounds: scalability.
AN EMAIL from Chairman Hickson resolves an ambiguity in the
nav element of HTML 5.
One of the new things HTML 5 sets out to do is to provide web developers with a standardized set of semantic page layout structures. For example, it gives us a
nav element to replace structures like
This is exciting, logical, and smart, but it is also controversial.
The controversy is best expressed in John Allsopp’s A List Apart article, Semantics in HTML 5, where he worries that the new elements may not be entirely forward-compatible, as they are constrained to today’s understanding of what makes up a page. An extensible mechanism, although less straightforward, would offer more room to grow as the web evolves, Allsopp argues.
We’re pretty sure Ian Hickson, the main force behind HTML 5, has heard that argument, but HTML 5 is proceeding along the simpler and more direct line of adding page layout elements. The WHAT Working Group Mr Hickson chairs has solicited designer and developer opinion on typical web page structures in order to come up with a short list of new elements in HTML 5.
nav is one of these elements, and its description in the spec originally read as follows:
The nav element represents a section of a page that links to other pages or to parts within the page: a section with navigation links. Not all groups of links on a page need to be in a nav element — only sections that consist of primary navigation blocks are appropriate for the nav element.
“Primary navigation blocks” is ambiguous, imo. A page may have two nav blocks; the first is site-wide naviagtion (“primary navigation”) and within-page links, eg a table of contents which many would term “secondary nav”.
Because of the use of the phrase “primary navigation block” in the spec, a developer may think that her secondary nav should not use a
Chairman Hickson has resolved the ambiguity by changing “primary” to “major” and by adding an example of secondary navigation using

Thanks largely to the success of the iPhone, Webkit, in the form of Safari, has been a surprising force for good on the web, raising people’s expectations about what a web browser can and should do, and what a web page should look like. — 12 July 2009
