14 · Page Integrity when Zooming
Most browsers allow text and images to be enlarged through a zoom feature or text-resize. This has become more and more useful as web developers appear to be reducing the general size of fonts used which can affect those with visual acuity difficulties and older people. Zooming can improve readability but there are times when it also affects the layout of websites.
