The note at the bottom of the first section (About formatting text (CSS versus HTML)) says -
"You can combine CSS and HTML 3.2 formatting within the same page. Formatting is applied in a hierarchical manner: HTML 3.2 formatting overrides formatting applied by external CSS style sheets, and CSS embedded in a document overrides external CSS."
Please be aware that embedded CSS will ONLY override external CSS if the external CSS link is closer to the tag than the embedded CSS (i.e., it comes earlier in the flow of the document). If the embedded CSS comes first in the flow of the document, it will be overridden by the external CSS instead.
How can you set the colour in HTML without having to create a CSS style sheet? In the tutorials, there is a smal box after the 'Link' box - you have the 'Point to file' box, then the 'Browse for file' then there was another box which, when opened, gave you the background colour options - you have one in the CSS selection called bg (background colour)
How can you set the colour in HTML without having to create a CSS style sheet?
You cannot. The separation of presentation from content requires that such changes be made in your CSS, and this is how DW does it. Any color specification in the current version of XHTML and in HTML5 is deprecated in favor of CSS. Which tutorials are you referring to? If Adobe tutorials, then they should be changed to reflect the current version of DW.
Notice that in the section called "Set HTML formatting in the Property inspector", below the paragraph regarding "Class", there is the statement "Use the Style menu to do any of the following:". This is erroneous. It should say "Use the Class menu to do any of the following:". The following comments definitely apply to the options found on the Class menu.
Note that in the section under "Set HTML formatting in the Property inspector" called "Target", there are 4 options listed : _blank, _parent, _self and _top. There should be a fifth item added to this list called "name". If a link bearing this target attribute is clicked, and if there is already a window open that already has that name, the link will open in that existing window rather than opening a new one. While this is a legacy usage from the antique days of frames, it still has some value (in HTML5, where it is still a non-deprecated usage) by preventing a series of links from each opening in a new window - rather they will all open in this one window (overwriting the previous 'occupant').
