How to find where browser breaks a paragraph of text

Question

I need to add line breaks in the positions that the browser naturally adds a newline in a paragraph of text.

For example:

This is some very long tex

Answer 1

Maybe an alternative: do all line-breaks yourself, instead of relying on the browser. Place all text in pre tags, and add your own linebreaks. Now at least you don't have to figure out where the browser put them.
