Dreamweaver tutorial: The layer reachs his to apply

Layer (Layer) it is element of page of a kind of HTML, you can locate it the aleatoric position on the page. The layer can include text, image or other HTML documentation. The occurrence of the layer makes the webpage is extended from 2 dimension plane three-dimensional. Can make the element on the page has jackknife and complex position. Above all, see next pictures please:

We do a layer above all

1, in " the window " menu ＞ is chosen " layer ", Or dot " insert " object of menu ＞ layout＞Choose " layer " .

2, a layer shows in the page.

3, adjust a handle to pull the measurement that uses control layer through the black all round

4, the choice handle that pulls the top left corner that eat a layer can move the position of the layer.

5, it is OK to click a mark pitch on a layer.

6, can insert in the layer other any elements include picture character to link form to wait.

A lot of layers can be drawn in a page, these layers can be listed in layer face plate. Also can overlap each other between the layer. Layer face plate can adopt bill of fare " the window " menu ＞ is chosen " layer " open.

We need to undertake explanatory to a few concepts here. The layer has the property that conceal and shows. After a this is a layer principal property is mixed, the behavior photograph of respecting was united in wedlock to become important parameter. Click the left of list of layer face plate, can hit switch to close an eye. The eye is earned and shut those who express a layer to show and conceal.

The layer still has an idea is number of plies, when number of plies decided jackknife which layer above which layer is in below. Of the layer that for instance number of plies is １ in number of plies for the layer of 2 above. Change number of plies can change the jackknife order of the layer.

There still is a parameter to prevent a jackknife namely above layer face plate. Once pitch on, page middle-level cannot overlap. 　

The layer still has a kind of filiation namely subordinating relation. Be so denotive in layer face plate.

The Layer2 in the graph hangs in Layer1 below. Layer1 is father layer, layer2 is child layer. Procrastinate in the page move Layer1, layer2 also is moved accordingly rise. Because of them already catenary was together, and Layer2 be subordinate to belongs to Layer1. Father layer shift can be affected child layer. Mobile Layer2 layer, layer1 layer is not moved. Namely child the layer won't affect father layer.

Should establish method of such a kind of subordinating relation very simple. Bolt by Ctrl in layer face plate will child the layer procrastinates drag father layer can.
