Question

I want a selector engine, with not many features, that is very very small.

I only need to identify by tag, id, and class – and be able to nest those things…

// select info paragraph within content area
#content p.info

// change headings above size h3
h1, h2, h3

I don’t need to check if the tag as an attribute which matches a regex pattern or anything like that. I want only to use fast selection methods, on well formed HTML.

I can only find full featured libraries online, which all weigh in around 3K – which I feel is far too much for a small job.

Answer 1

I do not see what is wrong with native javascript?

document.getByElementId(...);
document.getElementsByClassName(...);
document.getElementsByTagName(...);

Or even this (can be used in all modern browsers [including IE8+]):

document.querySelectorAll(...);
document.querySelector(...);
