To overlap or layer HTML elements Set the position of the elements to relative absolute or fixed Then use zindex to specify which element is on top or below For example TOP BOTTOM #top #bottom { positionfixed top0 left0 } #top { zindex9 } #bottom { zindex8 }.

Styling Your LayersLayering with Div TagsUsing Absolute PositioningSetting The LayersNested Div LayersCleaning It UpSummaryWhile the div tag can be used to separate the code as shown in listing 1 the real power of layers is when you add attributes to the div tags and then manipulate each div block independently with CSS and JavaScript In listing 2 you’ll see that each div tag has been given a style attribute which manipulates the content While the listing 2 presented different blocks being manipulated with formatting the idea of layers implies moving things around on the page as well as putting such blocks on top of each other This can be done using the position attribute For positioning you can set things to an absolute position or a relativeposition We’ll cover absolute positioning to take control of your layers! Absolute positioning allows you to state specifically where you want the block of HTML in your div tag to appear This positioning is based upon a coordinate system where 00 is the upper left corner of the parent element that contains your div tag When positioning elements you can set the top and the left positions using the top and left attributes You can also control the width and height of the area the block will use with the width and height attributes! If you don’t specify the width and height then the div tag will default like any other HTML tag to using the space needed In Listing 3 you can see the previous listing has been modified so that many of the div tags have absolute positioning You can see the results in Figure 3 As you saw in listing 3 blocks can be set on top of each other If you put an image on top of text you’ll likely not be able to see that text If you put text on top of an image then you will likely see both You can control which block is on top (or higher in a stack) using the zindex property Setting the zindex to a higher number will move a block towards the top of the stack By default the current element is given a zindex of 0 In Listing 3 the text and image were displayed without a zindex being specified In Listing 4 a zindex has been added in order to control the display You should note that if a div is nested within another element then the absolute positioning will be based on the parent element’s position and not the page The div elements in Listing 4 are all within the div that is style “DivStyle” near the top As such the positioning is relative to where that div is displayed In listing 5 the absolute positioning of the DivStyle is moved to 10 100 When you run Listing 5 you’ll see that not only does the main div move down to that location but all the embedded div positions move relative to the change as well You might have noticed a few things are still not right with the listing For example the “ONE” text is still not seen This is because it’s relative position is the same as the div for the “TWO” text You can adjust the positioning to show both text items You might have also noticed that the “End of Page” text only appeared at the end of the page with the first two listings When items are rendered in absolute positions they are shifted out of the normal flow the page uses for rendering In the case of this listing the “ONE” text “TWO” text and image are all placed in absolute positions This shifts them out of the normal order which in turn moves the “End of the page” text as the second line This article scratches the surface in showing you how you can use absolute positioning to create layers with blocks of HTML code You also saw how to control which content is in the higher layers You can download the listings and images from this article from here and then play around with the positions and order!.
