Choose Adaptive to create a palette using a representative sample of colors in the graphic without any dithering
(mixing of small spots of colors to simulate additional colors). Choose Web to create a palette of web-safe colors that
are a subset of Windows and Mac
OS system colors. Choose System (Win) or System (Mac) to create a palette using
the built-in system color palette. This choice may cause unexpected results.
Select Interlace to load the images progressively by filling in missing lines. If this option is not selected, an image looks
fuzzy and gradually becomes clear as the image reaches full resolution.
JPEG Options (Image Quality) Determines the trade-off between compression (for smaller file sizes) and image quality
for each JPEG image created. Low produces the smallest file and lowest image quality.
JPEG Options (Format Method) Determines how quickly JPEG graphics display when the file containing the image is
opened on the web. Choose Progressive to make the JPEG images display gradually and in increasing detail as they are
downloaded. (Files created with this option are slightly larger and require more RAM for viewing.) Choose Baseline
to make each JPEG file display only after it has been completely downloaded; a placeholder appears in its place until
the file displays.
Ignore Object Conversion Settings Ignores Object Export Options applied on individual images. See “ Apply Object
export options ” on page 436.
Advanced options
Use the Advanced area to set CSS and JavaScript options.
CSS Options Cascading Style Sheets (CSS) are a collection of formatting rules that control the appearance of content
in a web page. When you use CSS to format a page, you separate content from presentation. The content of your page—
the HTML code—resides in the HTML file itself, while the CSS rules defining the presentation of the code reside in
another file (an external style sheet) or within the HTML document (usually in the Head section). For example, you
can specify different font sizes for selected text, and you can use CSS to control the format and positioning of block-
level elements in a web page.
• Embedded CSS When exporting to XHTML, you can create a list of CSS styles that appears in the Head section of
the HTML file with declarations (attributes).
If Include Style Definitions is selected, InDesign attempts to match the attributes of the InDesign text formatting with
CSS equivalents. If this option is deselected, the HTML file includes empty declarations. You can edit later these
declarations in Dreamweaver.
If Preserve Local Overrides is selected, local formatting such as italic or bold is included.
• No CSS Selecting this option omits the CSS section from the HTML file.
• External CSS Specify the URL of the existing CSS style sheet, which is usually a relative URL, such as
“/styles/style.css.” InDesign does not check whether the CSS exists or is valid, so you’ll want to use Dreamweaver to
confirm your external CSS setup.
JavaScript Options Select Link To External JavaScript to run a JavaScript when the HTML page is opened. Specify the
URL of the JavaScript, which is usually a relative URL. InDesign does not check whether the JavaScript exists or is valid.

Editions reader software.
