You may have read in such a hassle because you have bought a new phone and try to describe your problem below. If you want to run the Bitcointalk’s site in Dark mode on Chrome, you can use the user script. You can use extension called Stylus or Dark Reader. They will help change the layout of the site and the site will look like the dark mode of your phone. The problem you mention, where text is underline and growing up, is probably due to the default settings of your browser or phone. If you use a rech-text editor, it can change the style. If you see this problem in Chrome, it may be due to your phone’s browser settings, or the editor that you are using is behaving like that. If you wish, you can check the style settings of the editor or use special app to ensure the correct text size and format.
