Vivaldi will adapt as you browse the web. A clean and modern interface to complement the content you are browsing. It’s also highly customizable – don’t like the tabs on top? Simply put them where you want, bottom, left or right.
The idea behind single page applications (SPA) is to create a smooth browsing experience like the one found in native desktop apps. All of the necessary code for the page is loaded only once and its content gets changed dynamically through JavaScript. If everything is done right the page shouldn’t ever reload, unless the user refreshes it manually.
Often you run into CSS issues with different browsers, and one way to easily make browser-specific CSS is if you have a browser class added to the body tag of your theme. That way you can for example just add .ie8 .myclass { cssfix } to specify CSS that will only be read by a certain browser (IE8 in this case).
