Using transparent elements in web design started to become increasingly common in 2013. The fact that the improvements in CSS enabled designers to have much better control and freedom with this feature certainly had a lot to do with this growing trend and today designers only need one line of additional code to achieve this potentially stunning effect.
A significant amount of transparency is used as a back drop to typography to give it more emphasis and to break up the contrast with the background picture. It is also heavily used in moving sliders and to bring product images more to the fore. It must be said that the levels of transparency can be over done, especially when used for text which can make reading hard. The examples we have listed below do not fall in to this trap in our opinion and hopefully they provide some good inspiration for your own web designs using transparency.
