How to link to specific line of text in page, using only URL?

Question

I am curious if there is a way to use only a URL to send someone to a specific line at a given page. Citebite does this, however it links to a cached page instead of the act

Answer 1

Depends on the situation:

1-Your own content

a. Simply add a href id, and then send a link to that (http://exmaple.com/document.php#myLine)

b. For a more advanced solution, you can scroll to a specific area and highlight it using javascript, basically you call something like this: http://example.com/document.php?scrollX=100&scrollY=230

and in your PHP code you have a function like this:

You can also use JQuery and do more fancy things like highlighting text or changing CSS values depending on the arguments

2-Someone else's content

You cannot directly link to a specific line or area without a browser extension or an external service like CiteBite, however with some hackery you can build your own little service that displays the website and run your own JS on it (think iFrames or something like that)
