A simple link <a href="http://google.com">simple</a>
will open the page inside the reader.
The only way to navigate back to the comic (and the reader) is by hitting the back key of the keyboard.
Same happens if target is set to _self
like <a target="_self" href="http://google.com">Link</a>
.
A link with target set to _parent
like <a target="_parent" href="http://google.com">Link</a>
will open the page inside the reader. As above, the only way to navigate back (to the reader, in this case) is
by hitting the back key of the keyboard.
