© 2010 Delmar Cengage Learning Positioning Objects with CSS With CSS page layouts, you use containers formatted with CSS styles to place content on web pages –images –blocks of text –a Flash movie –any other page element The appearance and position of the containers is set through the use of HTML tags known as div tags. –you can position elements next to each other as well as on top of each other in a stack

© 2010 Delmar Cengage Learning Using Div Tags versus Tables Tables Control the appearance of your web page Static and difficult to change on the fly Div Tags Control the appearance of your web page Stack your information in a vertical pile Treated as their own documents so you can easily change its contents

© 2010 Delmar Cengage Learning Behaviors Behaviors in Dreamweaver are simple action scripts that allow you to incorporate interactivity by modifying style or content based on variables like user actions

© 2010 Delmar Cengage Learning Understanding Div Tags Div tags are HTML tags that define how areas of content are placed and formatted on a web page Div tags can be used to designate different colors for blocks of content, text that uses a CSS style, and many other properties AP Div Tag is a div tag that has a specified, fixed position on a web page (absolutely positioned)

© 2010 Delmar Cengage Learning Using CSS Page Layouts Dreamweaver provides 32 predesigned layouts in the New Document dialog box These layouts are used to place the page elements, rather than using tables Because div tags use CSS for formatting and positioning, they are the preferred method for building content for web pages Dreamweaver provides information about the blocks of CSS content on web pages by using outlines in Design view

© 2010 Delmar Cengage Learning Viewing CSS Layout Blocks As you design web pages using div tags for page layout, you can use Design view to see and adjust CSS content blocks. –Defined by dotted borders

© 2010 Delmar Cengage Learning Understanding CSS Code When you view a page based on a predesigned CSS in Code view, you will notice helpful comments that explain sections of the code –The CSS rules reside in the Head section. –The code for a CSS container begins with the class, or name of the rule, and is followed by the ID, or the name of the container. –A pound sign (#) precedes the ID. –The code that ties the rules to the content is located in the body section.

© 2010 Delmar Cengage Learning Edit Content in CSS Layout Blocks Easy to modify the properties for individual styles to change the way the content is placed or formatted on the page During the process of creating a page, you can attach an external style sheet to the page –External and internal style sheets for page layout in the CSS Styles panel

© 2010 Delmar Cengage Learning Understanding Table Modes Grid layout on a page, such as a chart with text and numbers Some web pages based entirely on tables and some contain tables inside CSS layout blocks Standard or expanded mode

© 2010 Delmar Cengage Learning Creating a Table: Standard Mode Useful when you want to create a table with a specific number of columns and rows Use the Table dialog box to set: –Rows, columns, border thickness, table width, cell padding, and cell spacing Nested table is a table within a table

© 2010 Delmar Cengage Learning Expanded Tables Mode Allows you to change to a table view with expanded table borders and temporary cell padding and cell spacing Easier to actually see how many rows and columns you have in your table The Expanded Tables mode allows you to see each cell clearly

© 2010 Delmar Cengage Learning Planning a Table Sketch a plan for a table that shows its location on the web page and the placement of text and graphics in its cells Decide whether to include borders around the tables and cells. –Setting the border value to 0 causes the table to appear invisible, so that viewers will not realize that you used a table for the page layout unless they look at the code

© 2010 Delmar Cengage Learning Setting Table Accessibility Preferences To make a table more accessible to visually handicapped viewers, add –Table caption –Table summary (does not appear on screen) –Table headers Can be placed at the top or sides of table Are automatically centered and bold

© 2010 Delmar Cengage Learning Resize, Split, and Merge Cells You can resize the rows or columns manually or by entering numbers in the properties inspector You can also take one cell and split it into two or more cells You can take two or more cells and merge them into one cell

© 2010 Delmar Cengage Learning Insert Images in Table Cells Use the Image command on the Images Menu on the Insert panel Drag it from the Assets panel into cell

© 2010 Delmar Cengage Learning Aligning Images in Table Cells You can align graphics horizontally and vertically within a cell –Use the Horz (or Vert) alignment option in the Property inspector To control spacing between cells, use cell padding and cell spacing

© 2010 Delmar Cengage Learning Formatting Cell Content Select the contents in the cell, then apply formatting to it Can format each item individually or select the entire cell and format it

© 2010 Delmar Cengage Learning Formatting Cells Different than formatting cell content Can include setting properties that visually enhance the cell appearance –Cell width, background color, alignment Select the cell or place the insertion point inside the cell, then choose the cell formatting options in the Property inspector
