About this object You can create a layer object in NN4 in one of three ways. The first two ways use NN4-only syntax: the tag in HTML and the new Layer() constructor in JavaScript. The tag offers numerous attributes that establish the location, stacking order, and visibility. These attributes, in turn, become scriptable properties. If you create the layer through the constructor, you then use JavaScript to assign values to the object s properties. The third way to create an NN4 layer object is to assign an absolute-positioned style sheet rule to a block-level element most typically a DIV element. This is the way that IE4+ and NN6 do it, too. In practice, however, a positioned DIV element is not as robust (from rendering and scriptability standpoints) in NN4 as a genuine LAYER element. Therefore, it is sometimes necessary to branch a page s code to use document.write()for a tag in NN4 and a
