Fluid Layout Techniques for

Widgets

Daniel Herzog, Vodafone

The web & resolutions

Easy topic.

Available space is a de-facto standard.

Mobile browsers mostly zoom.


The web & resolutions

The physical size of the monitor is not respected.

High res displays mean small fonts, images, GUI.

Nokia N96, 2.8 inch display.

Phones running on S60 V5: 640 x 360

Nokia 5800 music, 3.2 inch display

Use media queries to switch to high dpi mode.


@media all and (min-resolution: 200dpi){ body {font-size: 22px}}


Solutions in detail

Only use them at their native resolution.

Maybe provide alternative versions.

When you don‘t know your images:


img {max-width: 95%;

}


Solutions in detail

Rules for images mostly apply

Very important to keep big enough.

If possible: Stay scalable with SVG.



Solutions in detail

SVG?


W3C standard for years.

Complex and powerful.

Widely available in most browsers today.

Just not on IE and IE based stuff.

Made for scaling.

SVG!


A little demo

SVG in your widget

Pixel-perfect rendering of that vector, size that fits.


object {width: 20%;

}

<object type="image/svg+xml" data="busy.svg"> <img src="the-fallback-busy.gif" /></object>

HTML

CSS

Even more resolutions

Portrait and landscape mode.

Docked mode. In portrait and landscape!


One more: Resize yourself.

function myResize() { if (widget.widgetMode === "application") window.resizeTo(screen.availWidth, screen.availHeight);}

// Do initially!myResize();

// And when the orientation changeswidget.addEventListener("resolution",myResize,false);
