3 :: The Basics of Client-side Programming : HTML, CSS, JavaScript & the DOM API (Duckett-JJ Introduction)
Client-side Web Programming Basics - Web developers have THREE masters 1. browser - adhere to standards so page is rendered correctly and predictably - no quirks 2. user - come for the style and pizzazz, stay for the content (content is king) 3. search engines: SEO & search engine bots (web crawlers or spiders or robots) - Modern web development assigns: 1. structure to HTML 2. style and layout to CSS 3. behavior to JavaScript. - Web development prototype tool - see first assignment!! Wyatt's Thimble START - mdn: Web Technology - HTML, CSS, JavaScript, DOM Hello Page / the code CLIENT! Web programming integrates three different technologies: HTML, CSS & JavaScript When people say web programming is easy, they often think it is simply HTML. Not even close. - mdn: HTML basics NOT a programming language markup language element = opening tag + content + closing tag tags scaffolding container for content attributes provide extra / essential information to the tag - mdn: CSS basics NOT a programming language style sheet language - apply styles to selected elements from HTML rules selector* declaration block declaration property: value styles applied to html layout: hardest to control - mobile first box model: MBPC grid colors text, font, size - mdn: JavaScript basics IS a programming language variables comments operators loops branch on conditions functions events - DOM API DOM document object model (wikimedia) DOM is how JS interacts with html and css DOM built when page is loaded JavaScript uses the ID of an element to get access to that element (usually) var ref = document.getElementById( IdOfElement ); ref.innerHTML = "<h1>The new element to insert into document!</h1>" #META: how does the 'h1' tag above NOT behave like an 'h1' tag?
4 :: HTML : Structure & Organization using markup tags (Duckett-HC Ch.1-5)
HTML is not a programming language; it is a markup language that defines the structure of your content through the use of markup tags that look like this: <body> - w3schools.com w3schools.com - less detailed, but solid w3schools HTML Tutorial W3 Schools: Try It editor html tags by category - MDN: mozilla development network mdn: HTML Intro - more depth Markup Tags / Elements: - usage each tag pair (open/close), together with its contents, defines an element. use lower case for tags properly nest elements -attributes provde more information about element attached to the open tag of the element quote attribute values class, id, src, charset, href, type, title, style, alt, rel <a href="http://jbwyatt.com">wyatt</a> <img src="IMG/doggy.jpg"  alt="my doggy"> - categories inline: no new line, takes up only width it needs <span class="xyz">content</span> OR block: always starts on new line - takes up full width self-closing (empty - no content): <img> <br> <hr> <link> <input> OR opening & closing tag: <html> content </html> <div> content </div> <p> content </p> - page loaded and DOM built - WAIT for this to complete before applying JS! DOM document object model (wikimedia) - mdn: head tag / meta <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>My test page</title> </head> <body> <p>This is my page</p> </body> </html> - mdn: text structure tags div, p, h1-h6, header, footer list tags ol, ul, li emphasis tags em, strong, b, i, u group inline elements, no visual change , apply style or "hooks" span forms form inut - mdn: hyperlinks hyperlinks are the most important tag in html specify a URL on the web http://jbwyatt.com specify http protocol specify a local URL (file path) relative path files in same directory going down going up ../ email mailto <a href="mailto:nowhere@mozilla.org">Send email to nowhere</a> - mdn: img tag show an image on your page <img src="doggy.jpg" alt="picture of my dog"> jpg, png, gif, bmp can use image as a link <a href="http://jbwyatt.com"><img src="doggy.jpg" alt="picture of my dog"></a> < - mdn: html tag reference html, head, meta, title, script, link body, h1-h6, div, p, header, footer br, hr comment ol, ul, li a, img - W3 Schools HTML Tag Reference - My HTML Examples
5 :: CSS : Style, rules, selectors, declarations, properties: values (Duckett-HC Ch.10-13, 15)
"Imagine an invisible box around every HTML element" CSS is not a programming language; it is a language that allows layout & styling of web pages. While HTML is used to define the structure and provide scaffolding for your content, CSS is used to style the page and control how it is laid out. Layout becomes complicated with different sized viewing windows (phones, tablets, desktops). -stylesheets external: <link href="xyz.css" rel="stylesheet"> internal: <style></style> inline: <tag style="property1:value; property2:value"> ... - DOM - styles are attached to DOM nodes DOM document object model (wikimedia) - rules specify styles rule => selector + declaration block declaration block = 1+ declarations declaration = property:value pair - rules allow you to style a page's layout color text w3schools CSS Tutorial CSS Demo Page mdn: How CSS works - layout "Imagine an invisible box around every HTML element" box model M -> B -> P -> C use this declaration to make percentages include border & padding box-sizing : border-box; (content-box does not count) - responsive use percentages (not pixels) for width of block elements width : 80%; (not 400px) media queries can determine size of viewing window @media screen and (max-width: 1300px) { body { background: blue; } } -flex box flex box .flex-container { display: flex; justify-content: center; } <div class="flex-container"> <div>111</div> <div>222</div> <div>333</div> </div> - css-grid layout example using a grid:

Window Object - window where browser displays page each tab has a window object location property of window = URL of the page 2. Document Object - the html page ( DOM ! ) DOM has properties, events and methods JS can access and change content JS can govern how user interacts Get and display a page (see p. 41) 1. browser gets html page & associated files 2. create a model (DOM) in memory nodes: elements, text, attributes 3. render page uses DOM and associated CSS (default or your css) c.

click here to demonstrate hiding/showing
// begin by hiding all divs of class 'notes' $('.notes').hide(); // when heading is clicked, show the first child object // using id of 'notes' just hides it at first $(".notesHead").click(function () { var obj = $(this); var nextObj = obj.next(); nextObj.slideToggle(500); });
