The APEX_CSS
package provides utility functions for adding CSS styles to HTTP output. This package is usually used for plug-in development.
This procedure adds a CSS style snippet that is included inline in the HTML output. This procedure can be used to add new CSS style declarations.
APEX_CSS.ADD ( p_css IN VARCHAR2, p_key IN VARCHAR2 DEFAULT NULL);
Table 4-1 describes the parameters available in the ADD
procedure.
Parameter | Description |
---|---|
|
The CSS style snippet. For example, |
|
Identifier for the style snippet. If specified and a style snippet with the same name has already been added the new style snippet will be ignored. |
Adds an inline CSS definition for the class autocomplete into the HTML page. The key autocomplete_widget
prevents the definition from being included another time if the apex_css.add
is called another time.
apex_css.add ( p_css => '.autocomplete { color:#ffffff }', p_key => 'autocomplete_widget' );
This procedure adds the link tag to load a CSS library. If a library has already been added, it will not be added a second time.
APEX_CSS.ADD_FILE ( p_name IN VARCHAR2, p_directory IN VARCHAR2 DEFAULT WWV_FLOW.G_IMAGE_PREFIX||'css/', p_version IN VARCHAR2 DEFAULT C_APEX_VERSION, p_skip_extension IN BOOLEAN DEFAULT FALSE);
Table 4-2 describes the parameters available in the ADD_FILE
procedure.
Parameter | Description |
---|---|
|
Name of the CSS file. |
|
Begin of the URL where the CSS file should be read from. If you use this function for a plug-in you should set this parameter to |
|
Identifier of the version of the CSS file. The version will be added to the CSS filename. In most cases you should set NULL as value. |
|
The function automatically adds ".css" to the CSS filename. If this parameter is set to TRUE this will not be done. |
Adds the CSS file jquery.autocomplete.css
in the directory specified by p_plugin.image_prefix
to the HTML output of the page and makes sure that it will only be included once if apex_css.add_file
is called multiple times with that name.
apex_css.add_file ( p_name => 'jquery.autocomplete', p_directory => p_plugin.image_prefix, p_version => null );
