Hello All,

 

In my attached file, I have tried to modify a simple slider as per my requirement. But, when I slide the slider, the target image gets displayed only after slide animation is finished. Can someone help?

 

Also on mobile, it is sliding very slowly. Please help.

 

I have attached my file for your reference.

Hello krishe, and Welcome to the GreenSock Forum!

 

It looks like you are animating very large images.. 1920x1080 .. you might want to resize the images to fit your slider width and height. And each image is like 1.6mb. I would optimize your images so they still look good but have a smaller file size.

 

Also what device are you seeing this on mobile? Is it android or and apple device?

 

You could try changing the CSS property left to x:

:

var fg = document.getElementById("fg");
    var one = document.getElementById("one");
    var two = document.getElementById("two");
    var three = document.getElementById("three");

one.addEventListener("click", function() {
      TweenLite.to(fg, 1.5, {css:{x: "0px"}});
});

two.addEventListener("click", function() {
      TweenLite.to(fg, 1.5, {css:{x: "-726px"}});
});

three.addEventListener("click", function() {
      TweenLite.to(fg, 1.5, {css:{x: "-1452px"}});
});

:

The reason its better to animate x over left is that the CSS left property does not animate on a sub-pixel level, only on a pixel level ( -726px ) .  But animating x property with GSAP you will be animating on a sub-pixel level ( -726.64858px ) .. which will make for a smoother animation.

 

You can learn more about why animating x and y are better than animating left and top.

Does that help? .. if not.. please create a codepen demo so we can test your code live in an editable environment.

 

Here is a video tut on how to create a codepen demo example.

 

Thanks! :)
