Always keep the small screen in mind when you’re preparing your docs. There are some W3C “mobileOK” guidelines to consider to ensure that your content meets requirements. Here are some highlights:
– No nested tables
– Tables must have more than one row and more than one cell per row
– There must be a Title element in the Head section, and it must not be blank.
– No frames. These don’t work well for search engines anyway, so it’s best to avoid them.
– No image maps
– Images must have height and weight measurements, and they must be in pixels
– Images must use alt tags, and there must be text in the tag (not blank)
– Transparent graphics for spacing: no large ones
These are just a few items. There’s enough, though, to consider. When you plan your content, think mobile.
