Is there any exercise that can help me making web screens responsive in web apps?

Hey Avneet, 

you can go to this lesson on CSS

Best regards, 

Hey Domingues,

I have already gone through this video. but that was not enough. I created a login web screen but its not responsive. how to do the same?

Hi Avneet Taneja,

I've done a 100% responsive system, so I used the Dublin theme and made some adaptations at hand, using isPhone(), isDesktop() and isTablet(). From there, you will be able to have your system responsive.
