Ravi Mendis 227.1 1 == What is Div#a Look? ==
Ravi Mendis 84.1 2
3 Much like ExcelLook, that vends excel pages, Diva look generates a Web 2.0 interface for DirectToWeb.
4 More specifically, it generates pages that are:
5
6 * Semantically-rich or **tables-less**
Ravi Mendis 95.1 7 * XHTML 1.0 strict compliant
Ravi Mendis 84.1 8 * Sans images, inline styles or presentation attributes
Ravi Mendis 105.1 9
Ravi Mendis 205.1 10 They make use of:
11
Ravi Mendis 227.1 12 * CSS **themes**
Ravi Mendis 205.1 13 * Scriptaculous **effects**
Ravi Mendis 227.1 14 * Javascript **widgets**
15 * Ajax

Ravi Mendis 105.1 17 = Why Table-less Markup? =
18
19 Scriptaculous, jQuery effects, etc work by manipulating CSS attributes.
20 Mostly they don't work very well on tables, if at all.
21 Furthermore, the more sophisticated widgets (like accordions) make use of effects and so don't function as they should without.
22
23 This is even more true for unobtrusive javascript for which table-less markup is usually a prerequisite.
24 Like jQuery, which takes this a step further, by applying functionality via CSS selectors.
25 (So for jQuery it is an absolute requirement).
Ravi Mendis 109.1 26
27 Therefore, if you are developing a Web 2.0/Ajax UI, the transition to table-less markup is an imperative.

29 === What is a Diva Theme? ===
30
Ravi Mendis 135.1 31 In ERDivaLook, or Diva for short, your application is not complete without a CSS theme.
Ravi Mendis 109.1 32 All images, layout, colors and font information are maintained in the CSS.
33
34 All your customizations to the look and layout of your application is also done in the CSS (and via D2W rules).
