I have a history timeline with CSS and jQuery and its working fine, but the issue I am facing with the width of li and their spacing from left, its not equal, I am trying to show each li with equal width and spacing from left and right equal and other thing, show the four li in first slide and show the last li in next slide, can anyone please help?
Here is the working JSFiddle demo
