Split a webpage into 2 with this bookmarklet

Cedric asked for Document-splitting in Web browsers and promptly got it (read the comment by Jeff Mesnil in Cedric’s blog entry).

Jeff Mesnil whipped up 2 bookmarklets in the space of less than one and a half hours that allows you to split a browser into 2 frames. How does it do that? It loads the current URL in a frameset consisting of 2 frames (both showing the same URL). A simple, yet genius, idea.

Here’s a screenshot of a blog entry split vertically:

Notice how it could be useful when cross-referencing something on the same webpage, particularly if it’s a long vertical-scrolling page. A perfect use case would be referring back to a long blog entry when making a comment.

Here’s the same page split horizontally.

There are probably lots of other use cases for a webpage splitter. Cedric’s in particular is this:

Just recently, I was reading an article that showed a figure at the top and which constantly referred to this figure in the rest of the article.

Thanks Jeff for writing the bookmarklets and Cedric for thinking of it.

Nifty, I did something similar back in January but tried to synch the scrolling between the two panes to faciliate reading from long pages.

That is very useful. Thank you.

Another useful feature, which I have come across recently is this extension:


When pressing Alt-O it shows you the outline of the current document, and let’s you quickly jump to places. (this requires that the current page has semantically correct hx Tags, obviously).

Split a webpage in your browser
You will love this! Now you can split your html document in your webbrowser (currently only in firefox and safari). A great solution. In the past I would open up two windows, resize them and put them next to each
