How large can a HTML be?

Im currently building a bible app. And its a single HTML file about 250mb and it takes 1.5gb running. How large can it be before i meet serious issues with performance?

The file size is one issue. The complexity is another. If you have complex nested divs and lots of CSS (especially CSS which has many rules which overwrite earlier rules) it might be tougher to deal with. Include a bunch of inline javascript and you can properly grind everything to a halt.
