Writing plain HTML is a thing of a very distant past, and the language itself (CSS) has advanced so much in recent years that it’s impossible to imagine what the web would look like without it. In the early days, much of webs styling could be achieved through HTML usage. At the same time, both HTML5 and CSS3 work closely together to achieve startling results in web design, application design, and even software design.

    material is shit. I used it in one of my wordpress theme project and had gone through lot of trouble. for pc and rich html5 browsers it is good but it just doesn’t cope with low end browsers like opera mini which is used by a great number of smartphone users because of it’s data saving policy. If you are going to make a responsive website with variety of mobile browser support, just don’t work anything related to material.

    1. WOW, do you want to have effects in opera mini?, probably an interesting framework is cascade framework, is the best for shit like IE and Opera mini. I think you had to investigate deeper before start a project, in my opinion material is an excellent framework for chrome, safari and firefox, It’s not the purpose of material works in all browsers, and in general could work perfectly in 90% of devices (chrome, safari and firefox) .
