There is a site with WordPress installed and a theme selected. I have created an HTML page for the site, but it wasn't looking well with the theme. So, I want to put the page on the site without any theme, and just the way I wrote the code, without disabling the theme from any other pages.
Is there an easy way to do it without messing with the theme? And if there isn't, then I am willing to modify theme files, but how should I go about it?
