I need to edit thousands of pages for a website with dynamic content added manually by the owner throughout 3 years, it has thousands of pages and I'm sure there is a better way to edit them without spending hours opening each one of them.I know it would be easy to just edit the styles.css but page dynamics like the positions of the google ad-boxes are individually edited inside the html of each page, so there is no way to solve this through css.Is there some sort of code, script and macro that can edit the pages at once?
How to edit thousands of html pages at once?
php;html;css
