Most people understand hidden text is something like white text on a white background, and know to steer clear of it. Let me show you an example of a hidden link. Normally a hidden link could be in several forms:
- hidden text that also happens to be hyperlinked, e.g. white text on a white background, and the text is a link
- using CSS to make hyperlinks that are tiny, like 1 pixel high text
- hiding links in something like the period in the middle of a paragraph of text
Now there๏ฟฝs nothing bad about changing the style of a link to some degree.
