We want to provide a greater visual impact, and make the code more efficient at the same time.
If you try the SVG file in your browser, you’ll see that the link only becomes active when you hover over each vector shape, indicated by a cursor change.
They can be linked using standard tags, with the href attribute and root svg element supplemented with the xlink namespace that SVG requires. The start of the file looks like this:Įach path outlines the shape of a Canadian province. As vectors, SVG can be infinitely scaled without loss in quality or lack of registration.Īs an example, I’ll use a map of lower western Canada, edited in Adobe Illustrator from Wikipedia’s SVG file of a Canadian map, then cleaned up in a text editor.As vector outlines, SVG files tend to be very small in file size.

Accurate SVG maps of every nation and the world are already available for free ( Wikipedia is a great resource, as is Régis Freyd’s MapsIcon project) with plotted outlines that can easily be turned into hyperlinked hotspots.Bitmaps tend to drop in quality or have an uncomfortably large file size when they are scaled, making them inappropriate for responsive websites.Īs an alternative, I would suggest using SVG, which avoids these limitations entirely:.

While you can scale the bitmaps that makes up the imagemap, the plotted points in HTML do not scale, “drifting” the hotspots out of registration with their associated visual area. Imagemaps take significant time to develop, due to the fact that the hotspots must be plotted by hand. While this works, imagemaps have several significant limitations in modern web design: This article originally appeared in net magazine issue 249.To create a clickable map on a website – for example, to create a world map for an company with several international distribution centers – imagemaps have been the traditional solution: bitmaps with linked “hotspots” written in HTML. Variations on the technique can used to force third-party content, such as embedded YouTube videos and Google maps, to also be responsive on your web pages. For taller or wider drawings, increase and decrease the padding-bottom value, respectively. The padding represents the aspect ratio of the SVG illustration: padding-bottom: 100% assumes that the SVG file is as wide as it is high. This combination of absolute and relative positioning with padding-bottom constantly maintains the SVG drawing inside a responsive 'window'. In the host HTML document's embedded style, or in a stylesheet linked to the document, add the following: svg Let's change that while adding to the interactivity of the linked areas. Copy and paste the edited SVG code like so: Ĭurrently, the SVG document takes up the entire space of the viewport, and the paths are filled with black. There are several ways to integrate interactive SVG into a web page: as an object, an iframe, or with the code added directly into the page. Links in SVG are written in the same way in HTML, with the addition of an xlink prefix to href attribute: Īfter linking each path, look at the SVG file in a browser: the exact outline of the Alberta province becomes the hotspot area of the associated link, and scales with the document and viewport window.

It's straightforward to clean up the code: remove comments, prolog, doctype as well as any attributes we don't need.
