CA Professional Web Site Development Class 24 - Print Styles, DW Templates & Library Items

External Style Sheets Use external style sheets for Web sites Allows use of same styles for all pages on site Makes it easy to change appearance and layout of elements sitewide Can have multiple external style sheets Creating an external style sheet: File > New > CSS Export internal styles Create new style rule in external style sheet Or, just copy and paste into new style sheet

External Style Sheets Linking external style sheets: If you export styles or create new styles using external style sheet, DW creates link for you Link button in CSS Styles panel Options: File/URL: location of style sheet (good to put in ‘styles’ folder) Add as Link / Import - usually choose link Media type

Media Types Can create different style sheets for different media: All (default) Screen (computer monitor display) Print Handheld - becoming obsolete? Usually select “all” or create screen and print styles

Print Style Sheets Must think in terms of print output Plan for black & white Inch measurements for margins, padding Fonts in point sizes, serif fonts for readability Layout issues: One-column layout is easiest to read in print Unfloat floats Use static positioning for all elements Background images do NOT display (usually) Set background color to white

Print Style Sheets (continued) Elements not needed in print version: Navigation Links Forms Etc. Print-specific styles: [:first | :left | :right ] { … } (e.g., margins) (support may be spotty) Properties: page-break-before/page-break-after: [auto | always | avoid | left | right ] page-break-inside: avoid; (tries to avoid page breaks inside an element)

Print Styles Widows & Orphans Widows - lines continued from previous page Orphans - lines stranded at bottom of page Example: p { widows: 4; } - no less than four lines at top of page if paragraphs continues over page break (or pulls whole paragraph to that page) p { orphans: 2; } - no more than two lines at bottom of page for continued paragraph Repeated headers/footer Position: fixed

Exercise: Create a Print Stylesheet Open your float layout Copy CSS to external style sheet Save as ‘screen.css’ Save copy of stylesheet as ‘print.css’ Create link in html doc to print.css Choose media type ‘all’ for now so we can see styles Edit print.css …

Exercise: Print Style Sheet Make #main_nav { display: none; } Remove float from #ltCol and #rtCol (plus #mainContent and #sidebar) Remove background images Give margins to body, remove text centering Make fonts point sizes, serif font on body text Consider source order of code (main content first) Add widow/orphan control

Exercise: Print Style Sheet Preview your page in browser What else could you do to improve? Change media type to ‘print’ Add link to screen.css as ‘screen’ Preview in browser Print out (CS22 printer)

Dreamweaver Templates, Library Items & Snippets DW templates let you create preformatted page designs as basis for new pages on your site: Repeated elements (non-editable) - such as navigation, masthead, footer, etc. Editable regions - where content will be entered Library Items are content assets (like copyright statement or contact info) that can be added to a page (but need not be on every page) Templates and Library Items can be updated and changes will propagate throughout site Snippets are chunks of code that can be inserted or wrapped around existing code (do not update)

DW Templates Create html page with all repeating elements of layout Insert placeholder content for editable regions Select content and choose Insert > Template Objects > Editable Region; give it a name Save as DW template DW will save inside templates folder Create new pages based on template from File > New > Templates tab Edit content inside editable regions, save as new html file When you update template, pages based on template will update

Snippets Select some code in HTML document Go to Snippets tab in Files panel Click New Snippet button DW will paste code in ‘Insert Before’ pane Give Snippet a name Give description (optional) Choose whether to wrap or insert as block If wrap, insert code for before and after Click OK Snippets are like shortcuts for pasting code - do NOT update if modified later
