Overflowing select highlight
What is the logic of the selection highlighting overflowing beyond the parent element?
In the attached screenshot, the top one is what I have currently, and the bottom one is a Photoshopped mockup of what I want to achieve.
To me it seems that the selection highlighting is almost largely random; I have not been able to find any definitive resources that explain what makes selection highlighting behave in which ways.
What should I keep in mind in terms of CSS and DOM when wanting to keep the selection highlighting reasonable?
Interestingly, I've wondered why SO doesn't have something like this so it's easier to copy code off an question/answer.
Actually, SO does have contained highlighting in the <code> blocks relying on overflow: auto;. <blockquotes> do not have contained highlighting.
Anyway, it appears there are a few ways to solve this problem (though, I'm sure there might be more). Use one of the following CSS rules to limit the highlighting of text to a specific element.
overflow: hidden;oroverflow:auto;position: relative;float:left;orfloat:right;
The working example below shows all four methods at work. Some are easier to work with depending on your needs.
