Tecate.js is a jQuery plugin which allows for in-page HTML validation. Tecate.js automatically checks for common HTML writing mistakes like matching tags, general bad syntax.
If found, automatically shows a popup with the errors descriptions and the lines on which they appear.
The library is might also be useful as a learning tool, where if one is learning HTML, they can drop Tecate.js in the header and be alerted when mistakes occur.
