Topics Covered
- Valid HTML
- Why is valid code important and what needs to be validated ?
- Validation strategies
- Styling with CSS
- Introduction to CSS
Software
- We will continue to use NoteTab light, a fee editor you can install at home. Get it form the NoteTab WebSite.
Browser extensions:
- Install it if you didn't do in week2: HTML VALIDATOR is a Mozilla extension that adds HTML validation inside Firefox and Mozilla.
- New: CodeBurner for Firefox (This is a HTML and CSS reference tool)
- Once you installed it, it is available through menu Tools->Codeburner for Firefox (or hit CTRL-ALT-D).
- This program also interfaces with the HTML reference at sitepoint online manual.
- Screengrab. Allows to grab portions of a screen or window.
The tidy program:
- Go to HTML Tidy for Windows
- Download the EXE version. You will get a *.zip file called tidy.zip
- Extract the single tidy.exe to some directory, e.g. c:\bin\
Teaching materials
- HTML and XHTML elements and attributes (continued)
- HTML and XHTML validation and repair
- Online HTML reference manual (at sitepoint, but you are free to choose others ...)
- CSS tutorial
- Online CSS reference manual
Classroom activities
- Monday
On Monday we will continue learning how to code HTML with a special focus on validity.
(1) Online documentation about HTML
- We will use http://reference.sitepoint.com/html (also availabe through the Codeburner Firefox extension)
- See HTML links (Manuals and short references) for others if you wish...
(2) A introduction to W3C Quality Assurance Tool set. It includes several tools
- http://validator.w3.org/ (Markup Validation Service)
- You can enter a URL, upload file or directly copy/paste code
- Supported formats (Sept 2009): HTML, XHTML, SMIL, MathML
- http://validator.w3.org/checklink (W3C Links Checker)
- http://jigsaw.w3.org/css-validator/ (on line CSS validation service)
- URL validation: You can enter either an HTML/XHTML URL or just a CSS
- Alternatively you can upload a CSS file (and pick the CSS profile).
- Other tools, e.g. a Feed validator are available from the Quality page ...
(3) Using web browser development tools
- Use of HTML Validator (install it if you didn't do it on week2). Basically you just go View-Source and look at the errors.
(4) Using Tidy inside NoteTab light
- This may not work (since Tidy must installed on your computer)
(5) Q/A Homework 2
- I will give you some time to work on homework 2 (due next Wednesday)
- Make sure to turn in valide HTML code !
(6) Using the tidy program (if time left)
- You can get various flavors from SourceForge. More precisely:
- Get the Windows binary version from http://www.paehl.com/open_source/?HTML_Tidy_for_Windows
- Unzip it somewhere on the harddisk (I stronly suggest the C: drive, we will discuss this with the Lab assistants, so wait)
- Then configure NoteTab light, i.e. hit CTRL-F7 and tell the editor where to find tidy.exe
- Alternatively (v.s. using a default repair configuration through NoteTab ), you also can install GuiTidy: http://www.paehl.de/tidy/ (scroll all the way down). It will give you more options. Advanced users will have to use the command line.
- Wednesday
We will start learning CSS, in particular
- Associating a stylesheet
- Inline Styles
- Embedded Style Sheets
- Linking External Style Sheets
- CSS Validation ( http://jigsaw.w3.org/css-validator/ )
- CSS Selectors
- Text styling (e.g. fonts, size, aligns)
- HTML div and span tags
- Backgrounds
- CSS “boxes” , positioning elements and text flow (if time only !)
Homework
Task: Create a little HTML page that spells out a proposition for a term project: creating a website with an online service (see homework 1)
- Think about objectives and requirements for your term project
- Create an HTML page (either in HTML 4.01 strict or XHTML strict) and write down a draft proposal
- Create an external CSS stylesheet that is linked to the HTML page
Constraints:
- HTML must include at least 3 titles plus paragraphs and lists (of your choice)
- Define a global default CSS rule or a rule for the body
- Define an extra rule for titles, paragraphs and list elements
Evaluation:
- I only will evaluate whether you comply with the constraints, the technical and design quality of the CSS and the validity of the HTML
- Details of the term project proposal will not be evaluated and it is not yet binding. However, I require that you you define certain key elements:
- Objectives: What is the purpose of the web site ?
- Audience: What is your main target audience ? Can others consult it/find it useful ?
- Functions: What kind of information / applications should the site provide
- Styling: Any ideas about its look and feel ?
- Other information: ???
Submission:
- Upload both the HTML and the CSS file to the Worldclassroom before start of week 4 wednesday lesson.
