If you were attentive you should see that the line width: calc( 12.5em ) is the trick here. Why? Let’s see all these widths like in pairs – exactly what we need browsers to do. The first pair is width: 80% (content) and width: 16.666% (sidebar) that does the job in calc() incompatible browsers, which will just ignore calc(). It is the callback (backup). It means that the minority of website visitors will see narrower sidebar on narrower viewports. And that should be perfectly fine for people using older browser versions. The second: width: calc( 100% - 15em ) and width: calc( 12.5em ). This is for newer browser versions which will override the previous width definitions

The recipe for the best user experience: Start with POSH, a simple set of heading/div pairs Add ARIA (role, aria-selected, aria-hidden, aria-labelledby) and tabindex attributes using JavaScript as these would be confusing if there was no behavior attached to the widgets. Use JavaScript to also plug a class on the component according to its type (accordion or tabpanel). Style the widget using the selector inserted by the script, this way containers are not hidden if there is no script support. Use cursor to style the tabs because those behave like buttons (default), not links (pointer). In case the component is displayed as a Tab Panel, style it as an Accordion before its tabs start wrapping (to accomodate user’s font-size) or at narrow widths...... ../..

Des sortes de “super éléments” ?__Les éléments générant un contexte de formatage block deviennent des sortes de “super éléments” ayant un certain nombre de super responsabilités : ils deviennent entre-autre garants de l’affichage de leurs enfants (qu’ils soient blocks ou inline).

Enforcing a maximum character length for text and textarea form fields is fairly easy to do.

I think there are many developers who don’t realize that most of the jQuery methods they use have native equivalents that require the same or only a slighter larger amount of code to use. Below are a series of code samples showing some popular jQuery functions along with their native counterparts.

What to do with these boxes? The six colored boxes (A, a, B, b, C, c) are "draggable", which means you can use your mouse to position them anywhere in the page. The input elements in the colored fieldsets let you set z-index and position values for each one of these six boxes. These fieldsets are color coded, which means a fieldset's background color matches the background color of the box it is supposed to style. Use Firebug to monitor in real time how these elements get styled.
