You should use simple keystrokes as opposed to paths, as this will lead to less code being produced. Start by creating your SVG icons in Illustrator. Along the way I'll explain the caveats you should be aware of when using SVGs. Having looked at the background to the issues surrounding accessibility with icons, the question arises as to how SVG icons can best be implemented. It is also possible to animate all or part of an SVG with JavaScript or CSS. On top of this, SVGs have more CSS properties, providing designers and developers with greater control over stroke width and colour (they can now create multicoloured icons, for example), as well as enabling them to target different sections of the icons individually. They scale to any size without losing detail, so look great on HDPI displays. Unlike font icons, you don't have to use workarounds to make them accessible: they already contain semantic title and description attributes. How font icons appear when a font fails to render Alternatively, if you don't want to write code, you can create graphics using software such as Illustrator, save them as SVGs, and the code will be generated for you. These are based on an XML markup language for describing two-dimensional vector graphics, which means you can create graphics using code. However, if for whatever reason SVG icons are not a possibility, see the boxout opposite for a guide to using icon fonts properly. Relying on CSS font positioning properties like line height and font size can be unintuitive when working with graphical glyphs, particularly when the icons need to align with images and text.įundamentally, using fonts to render vector images is a hack to get widespread browser support. If the font rendering fails, the icon will not display instead users get something like a square box, which doesn't mean much to anyone. If designers use their own CSS with a different font, a different icon will show. There are further problems with this approach. However, to make icon fonts accessible you have to include some extra code that browsers ignore but screen readers do not. They also boast wide-ranging support across all major browsers and versions. These are vector-based and therefore resolution-independent, and things like colour and position can be manipulated through CSS. However, altering icons remained a cumbersome process – changing the colour or resolution still necessitated the creation of a separate image, which would increase the size of the sprite. Readers were able to ignore the icons if they were for decoration purposes only, as there was no markup on the page.
