Tables represent quintessentially important elements in HTML5 and all previous versions as well, serving as the cornerstone data visualization tool in data-centric applications since the early days of Internet evolution.
GridView is rather important data-aware web control pertinent to ASP.NET framework; essentially, it renders the underlying data structures as HTML table. Following examples demonstrate novel CSS3 styling techniques applicable to HTML5 Table element and its sections.
HTML5 Tables typically contain multiple row tags
tr, which could contain either standard cell tags
td, or header cell tags
th. In addition to this, Tables could be enhanced with section elements:
thead and
tfoot tags used for the purpose of grouping header/footer content, correspondingly and
tbody tag for grouping together main content of the table. Each of these sections could be styled differently via CSS, thus are adding more “granularity” to formatting options.
Solution
For the purpose of didactic clarity, the proposed solution implements exclusively HTML5 and CSS3 features; nor JavaScript, neither jQuery is used.
Proposed solutions DO NOT use any graphic files (like .jpg, .png, .bmp, etc.), thus resulting in very small digital footprint and fast web page load. The entire solution is encapsulated in a single
.htm file less than 8kb in size, which is well below the typical size of any medium-quality picture file (file size could be even further reduced by removing the comment lines added for the clarity/readability).
Last but not least: solution implements pure client-side techniques without any need for round-trip to the server, thus it could run autonomously in off-line mode, pretty much like any standard downloaded application. Any major web browser on the client’s machine could serve as a platform, providing almost universal portability ranging from typical desktop – to notebooks – to tablets – to mobile devices (smart phones).
Usage
As mentioned above, the entire solution is encapsulated in a single text file. You can copy-paste the following code snippet (see Listing 1) using, for example, Notepad text editor, then store the file with .htm extension, and
voilà - that's it! Open the file in any major browser and see it up and running.

Design Note
In case of lengthy table it could be recommended to put
tfoot tag before
tbody, so the browser would be able to render the foot before processing the rest of the rows.
