Having an accessible website is not just a finesse, but a must. Although there are still problems with the inconsistent display of content between browsers, things are much better than in the past. This means that there is no excuse for disregarding accessibility when creating and updating your site.
Here are some accessibility tips to keep in mind when creating your site:
You Should Resist the Temptation to Use Images or Flash links on your site. This helps with accessibility, the spidering search engine and ensures that the navigation links can be traversed by using the tab key as well as the mouse. The ability to use the keyboard to get around the site is an important accessibility requirement to ensure that those who can not use a mouse for various reasons are not compromised by your site.
Make sure all images are tagged with alt tags or other text. This is a key accessibility requirement, to ensure that those who can not see the images or choose to navigate without images can see your entire site without disadvantage. Alt tags should be descriptive and relevant to each image, rather than generic or used as a location to insert irrelevant keywords for the image. Keep them in order and to the point – if the picture is that of a parachuting man, tag it as a parachute man. There is no need to prefix the word "image": & # 39; like many speech synthesis browsers will add this automatically, so the listener will be here & # 39; image image & # 39; if you also insert the word image!
When it comes to accessibility, one of the biggest hurdles can be Flash. Flash should be used only sparingly and only to add keys rather than important content. In addition to being slow to load, Flash is often deleted by firewalls or disabled in the Web browser. The accessibility of Flash content is very low because it is impossible for a search engine to know what a Flash banner displays. Therefore, use Flash carefully.
Be sensitive to your color scheme! Make sure you use colors that look good together and are easy to look at. So do not use colors that clash with each other, are too similar or too light to read easily on the screen. There are tools you can use to see how your colors will look with those with different types of color blindness.
Make sure you do not correct the font size, but rather allow visitors to change the font size to suit their needs. . Therefore, do not set the absolute size of pixels in your style declarations.
In summary, be considerate for your entire audience, who will also use a variety of browsers and monitors to view your site. It is there before running your site through a text-only browser such as Lynx to see how it displays there, and also run your code via a code validator to make sure the errors are corrected before you start .
