If I'm understanding correctly, you can rotate around the left side by using transformOrigin: "left 50%". To rotate around the center, use "50% 50%". e.g.

TweenLite.to(element, 2, {rotation:90, transformOrigin:"left 50%"});

This is from the API for CSSPlugin:

  • transformOrigin - Sets the origin around which all transforms (2D and/or 3D) occur. By default, it is in the center of the element ("50% 50%"). You can define the values using the keywords "top", "left", "right", or "bottom" or you can use percentages (bottom right corner would be "100% 100%") or pixels. If, for example, you want an object to spin around its top left corner you can do this:

    //spins around the element's top left corner
    TweenLite.to(element, 2, {rotation:360, transformOrigin:"left top"});
    The first value in the quotes corresponds to the x-axis and the second corresponds to the y-axis, so to make the object transform around exactly 50px in from its left edge and 20px from its top edge, you could do:

    //spins/scales around a point offset from the top left by 50px, 20px
    TweenLite.to(element, 2, {rotation:270, scale:0.5, transformOrigin:"50px 20px"});

Hi celopez16 :)

 

You can spin an element forever like this:

TweenMax.to(yourElement, 1, {rotation:360, ease:Linear.easeNone, repeat:-1})

Just an FYI - it's always best to start a new topic for your questions and provide a CodePen for us. Thanks.
