Issue making gif responsive

I tried adding the full size gif using visual composer single image and then through the text block method. The plugin works on the text block method but isn’t responsive as you can see in this screen capture https://www.dropbox.com/s/cytblibgpio8j35/Test%20page%203.png?dl=0

How can I make the gif that has Gif Animation Preview style applied and have it be responsive?
