8 Material So Far… HTML and CSS Purpose and Capabilities Syntax Tags / Properties How to Use Built a HTML5 standards compliant website (by tonight) Q: Are we done?

9 What’s to Come… Dissect existing sites and mockups into HTML and CSS components Use background images to spice up our websites Use CSS positioning to create modular and non-linear layouts A: Not yet… …of course Javascript, PHP, and MySQL Still to come

10 That’s More Like It…

Layouts?... o_0 A: The placement and interaction of your site’s components. A: Infinitely many… but some are more common and better than others.

18 Skip Photoshop for Now Insert “How to create a website mockup in Photoshop” here.

19 Step-by-Step From Mockup to HTML and CSS 1. Identify your site’s different components. 2. Create a that corresponds to each component. (Outside -> Inside, Top -> Bottom, Left -> Right) 3. Working from the outside in, translate each component into HTML. (Outside -> Inside, Top -> Bottom, Left -> Right) 4. Apply CSS.

20 Element ’s are our general layout building blocks/containers Used to logically group HTML elements Separate regions of code into functional regions “these HTML elements make up the menu system” Like span’s they typically have no visual effect on our HTML documents by themselves span’s are inline elements div’s are block elements What happens when we wrap a set of elements in div tags?

25 Mockup -> HTML & CSS Example HTML Completed embargo.zip > index.html

26 Mockup -> HTML & CSS Example Oops… Layout Totally Wrong? Nothing more CSS can’t fix Q: What happened? A: ’s are block level and naturally appear on their own line

27 CSS Properties: height, width Can only be set on block level elements and a few inline elements such as Example: div { width: 100px; height: 100px; } div { width: 100%; height: 100%; } Common Values: Pixels: 20px Percentage of parent: 100% Not set/auto: width of contents height: 100px; width: 100px;

28 height: 100px; width: 100px; CSS Properties: height, width …continued height: 100px; width: 100px; height: 100%; width: 100%; height: 100%; height: auto; width: auto; width: 100px; height: 100px;

29 CSS Properties: position Example: div { position: absolute; } Common Values: absolute Relative to closest parent who has its position set. If no parent qualifies, relative to document boundaries. Removes object from flow of document. Object takes up no space. relative Relative to the objects natural location. fixed Relative to browser window’s boundaries. Removes object from flow of document. Object takes up no space. static Don’t typically use this because it is already the default behavior.

30 CSS Properties: top/bottom, left/right Used in conjunction with position Example: div { position: absolute; top: 0px; left: 0px; } Common Values: Pixels: 10px

31 position Document Flow A B C code: div { position: static; }div { position: relative; }div { position: absolute; } span: “A” div: “B” span: “C” span: “A” div: “B” span: “C” span: “A” div: “B” span: “C” or div { position: fixed; }

32 top & left Effects div { position: static; top: 10px; left: 10px; } span: “A” div: “B” span: “C” span: “A” div: “B” span: “C” span: “A” div: “B” span: “C” div { position: relative; top: 10px; left: 10px; } div { position: absolute; top: 10px; left: 10px; } div: “B” top: 0px; left: 0px; 10px

33 absolute References top: 0px; left: 0px; A B A B code: div { position: absolute; top: 10px; left: 10px; } div { position: absolute; } #A { top: 10px; left: 10px; } #B { bottom: 10px; right: 10px; }

34 absolute vs. fixed Please see included absolute_vs_fixed.html file for demo

35 Positioning Worksheet positioning worksheet.pdf

36 How Do We Fix This? #sidebar { position: fixed; top: 0; left: 0; height: 100%; width: 200px; } #content { position: absolute; top: 0; left: 200px; height: 100%; width: 800px; }
