Make ASP generate pure html with no css and javascript

Hi, I've been working on an ASP.NET project, doing the HTML and CSS. ASP is adding a whole lot of it's own inline CSS code as well as all sorts of JavaScript. It also modifies my IDs sometimes. I can't see why any web developer would work with a system like this where you have to spend a lot of time just trying to override all the default styles that can't be turned off. Am I missing something here? I've looked for solutions but all I've found is advice to override the CSS or use JavaScript to remove the styles neither of which are real solutions to the problem.
