Spacer images should be assigned null ALT text, or alt=””. This way most screen readers will entirely ignore the graphic and would not even declare its existence. Spacer photos are disguised . images that pretty most websites make use of. coque iphone 6 The purpose of these people is, mainly because the identity suggests, to develop space in the page. Sometimes it’s difficult to create the visual screen you need, so you can stick an image in (specifying its elevation and width) and voli’, you have the excess space you may need.
Not everyone uses this null ALT text message for spacer images. A lot of websites stick in alt=”spacer image”. coque iphone Imagine how annoying this can be for a screen reader consumer, especially when you have ten of which in a row. A display reader could say, “Image, spacer image” ten moments in a line (screen viewers usually say the word, “Image”, before reading out its ALT text) – now that isn’t helpful!
