Expand div from bottom to top?

[Devotee007]

Hi,

 

My first post here, I guess it's a real newbie one... I searched and couldn't find any post with this question, so I hope it's ok. What I try to do is to have a div expand from the bottom up, but I can only get it to expand from top to bottom. How can I reverse this?

CSS:

.wrapper {
position:absolute;
top:40px;
left:40px;
width:430px;
height:0px;
z-index:1;
background-color:#000;
overflow:hidden; 
}

 

 

TweenMax.to(".wrapper", 1.2, {height:"430px", ease:Expo.easeOut});

Use a child element within the wrapper, absolutely positioned and bottom: 0;

 

Then tween the height of the child;

It sounds like you might want to animate a rectangular clipping path.  I had actually been wondering how to do the same thing recently, and found a helpful example in another thread.

 

I forked & updated it:

Masking/clipping custom shapes across browsers is kind of a nightmare, but clipping rectangles is well supported.  https://msdn.microsoft.com/en-us/library/ms530748(v=vs.85).aspx

 

Apparently clip rect is deprecated though...(?)

But clip path seems to work too:

Any experts feel free to weigh in or correct me if there's anything wrong with my examples, I'm still new at this too.

I saw that you edited your original question. Can we assume that you found a solution for your issue?

 

Just in case Clip Path is supported by all major browsers and can be animated using GSAP as shown in these demos:
