What is tweening?

How do you find broken links in GoLive?

What are actions in GoLive?

How can a page automatically load another page after a certain amount of time?

What can layers on a Web page be used for?

The Tween command in ImageReady automates the creation of additional frames in an animation. It does so by interpolating attributes of position, opacity and effect parameters, to generate a series of frames between two existing frames. In this way, ImageReady can significantly reduce the time required to create animation effects, such as having an object fade in (or out), or move across the scene.

If a page contains broken links, GoLive displays a bug icon next to the file name in the status column of the Files pane. In the document window, you can highlight elements causing a link error by choosing View > Show Link Warnings, or by clicking on the bug icon in the Main toolbar.

Actions in GoLive are scripts that are executed when triggered by specified events. An event can be something that the browser does (e.g. loading of a page), the user does (e.g. moving with the pointer over an image, or clicking something), or a point in time (e.g. in a timeline sequence). Actions can perform all sorts of things, from loading new images or pages, to opening alert or password windows, hiding and showing layers, or controlling the playback of sound or movies. GoLive provides a full set of pre-built actions ready for you to choose from (accessible via the Actions palette).

You can add a Refresh object to the head section of the page. You can specify the amount of time in seconds after which either the current page gets refreshed, or a different page gets loaded. Refreshing is useful if your page displays live content pulled from a database that changes over time (e.g. a stock ticker or news headlines). You might load different pages to present a slide show, for example, where each page contains a Refresh object to load the next page in sequence.

The content of layers on a Web page can be formatted and positioned independently of each other. This way you can have images overlap on a page, for example. You can show and hide layers triggered by actions (e.g. to display a drop-down menu when moving over a menu button). Using the Timeline Editor, you can animate layers (e.g. change the layer's position on the page over time).
