CSS3 gradients are now well and widely supported by most major browsers — except, of course, Internet Explorer. IE9 is the only active version to allow multi-stop gradients with transparency. Even so, gradients are a bit kludgy to apply in IE9 and more limited compared to gradients in CSS3. In IE 6-8, we can make limited gradients using an MS filter. IE10 will be the first Microsoft browser to fully support CSS3 gradients using the proprietary -ms prefix.

Photoshop adjustment layers are much like any other Photoshop layer. They sit somewhere above or below the other layers in your layer stack and can be used with effects, masks, and filters. An adjustment layer will affect all layers below it. So, for example, if we applied an orange solid color adjustment layer to our layer stack, then all layers below it would have an orange-ness to them.
