In-Depth Information
you visualize the hierarchy of structure in the file and also allows quick navigation
to its various components. Click any element to jump to its source. (Navigation
control can be configured using the structure view toolbar.) The
HTML
view is a
hierarchical tree of the page structure, the JavaScript structural view is a list of all
the functions and variables defined in the file, and the
CSS
view is more or less a
list of each the selectors specified by the file.
Go to declaration
This action works the same as it does with Java files. Selecting a symbol and exe-
cuting
Go To | Declaration
(
Ctrl+B
) takes you to the symbol's initial definition,
even if it's defined in another file. This feature works in the expected places in
HTML
,
CSS
, and JavaScript files, including
JavaScript function calls, variables, and parameters

tags (takes you to the
XHTML
schema)
■
References to external files through
src
and
href
attributes (anchors,
styles, scripts, and so on)
■
Stylesheet references through

or

If you do a lot of
HTML
work for web site design, you will find the new
Image Viewer
helpful. It lets you view images directly in the
IDEA
editor.
It even works in
HTML
image tags. Click the image reference, and then
select
Go To | Declaration
(
Ctrl+B
). This is a good way to verify that an
image you reference is the image you think it is!
TIP
Open in Browser
The
Open in Browser
feature lets you easily preview the currently open
HTML
file in the browser specified in the
General
settings panel. If all paths and refer-
ences in the file are relative to the file location, you're able to view the file as it is.
If paths are specified via aliased paths, references to the corresponding files may
appear broken. (Note that this feature is just for quick general preview.) To view
the file, select the
Open in Browser
command from the
View
or pop-up menu.

Refactoring web content
In addition to all the editor-related features already discussed, several refactor-
ing operations can be applied to
HTML
,
CSS
, or JavaScript files. The first two,
Move
and
Rename
, work similarly to the way they do with other types of files.
When you perform one of these refactorings,
IDEA
automatically corrects all
