From here to there - Links

Linking - the ability to embed hyperlinks in pages, is one of the most significant features of the web. The idea that a viewer could click on a word or a picture and immediately be taken to another page that provided additional relevant information was revolutionary.

  1. Review the Keywords and Reading guide questions at the top of this page. These will help you look for important ideas in the rest of assignments for this module.

  2. Read 2-3 of the Working with Links media.

  3. Working with Links - Open a new coding project. Collect all the links that you selected for previous assignments and add them to this project html file. Use all the link elements and tags to provide links to the sites, to your other projects and headings within this html file.
    Check the Email HTML Code tool for help with the mailto link.
  4. Review the grading rubric in the Working with Links assignment. Compare your work with the grading criteria. Do you understand the criteria and how your coding project will be evaluated? Any questions about the rubric and the grading process?
  5. Check your work. Use a HTML code validators such as HTML Validator to check the code you have written. Just copy your HTML code and paste it into the textbox in the online form.

  6. Submit the link to your coding project to the Working with Links assignment. Include any questions or comments you have about the rubric and the coding project evaluation process.
  7. AND Post a link to your project along with your comments and questions about this assignment to the Working with Links discussion.

  8. Review the work of 2 others - the page display and the source code. Post a note with links to those projects, and a brief description of your observations - anything that you learned from looking at these? Any ideas you have for using in your own work in the future? Post to the Working with Links discussion.

  9. Voyager public web page - If you do not have a Voyager account from another DeAnza CIS course this semester, you need to set it up. The instructions are provided CIS89A Voyager FTP If you have questions, ask as a post in the Link to Voyager discussion topic.

    Set up your Business/Computer Systems Account - If you haven't done this already, see Accessing Your Computer Account for more information. Enter your Campus Wide ID and birthdate (for security reasons!!). Following the lab agreement, click the checkbox to confirm and proceed. This will create a DeAnza Windows account.
    If your account has been successfully created, please close your browser. You need to wait at least 5-10 minutes to use your new account.
    Then Set up your DeAnza Voyager account. You will also be saving work to the DeAnza web server Voyager, so you will need a Voyager account as well. Use the same username and password to login to Voyager.

  10. If you already have a Voyager account, or once you have created your Voyager account, create a simple HTML file and upload it to the public_html directory in your Voyager account. This must be a text file with the type .htm or .html. You can copy the HTML from Glitch, but check that you are creating a new text file on your own computer.
    There are several ways to transfer files to Voyager. You can use any ftp application or web page development tool that provides file transfer to move your page source text file from your computer to your Voyager public_html directory.
    Note: some functions work fine with either http: or https: in the web address. Other sites will work with one but not the other. Try each one if you are having problems.

  11. FTP - For pages hosted on Voyager, transfer the HTML code text file with suffix .htm or .html to your Voyager public_html directory. Voyager is an SFTP server. To connect Voyager, enter the address sftp://voyager.deanza.edu into the host field.

    FileZilla (recommended) is open source software distributed free of charge under the terms of the GNU General Public License. FileZilla documentation including tutorials are available.
    Also see CIS89A Voyager FTP http://wikieducator.org/User:Vtaylor/CIS_89A_HTML_and_CSS/CIS89A_Voyager_FTP instructions. Instructions for downloading a different FTP application - Putty (PCs only) are included in the Voyager instructions .pdf. You only need one of these FTP applications.
    NOTE: Make sure the File protocol is "SFTP" otherwise you will not be able to connect to the server.

  12. Post a link to your web page in your Voyager account to Link to Voyager discussion.
    example : http://voyager.deanza.edu/~vtaylor/m18index.html
    ~username is a shortcut to your public_html directory in your Voyager user directory. username is always all lowercase. To access your web page files stored on Voyager - just http:// (not https://)
    Submit the Voyager page web address to the Voyager web page address assignment.

    NOTE: Throughout the course there are a number of discussion activities that require research and comments. These are important because they address topics that web developers need to know about. And you should be critically examining the site designs, layouts and usability. We will be look at site evaluation criteria in more depth later in the course. For now use this evaluation criteria to guide your review of the sites you visit. In your post for each of the research activities include a note about the site design based on one of the criteria in the evaluation description.

  13. Success Skills - Share it - Communication and Collaboration are becoming more important as we are expanding our personal and professional networks of contacts and businesses. Review 2-3 articles from Success skills - Share it. The internet is all about sharing - information and processes including web development. What do professional web developers do? Look at the .html and .css source code for the sites you selected. What do you see that is different from what you are creating with Glitch? How does the code determine what the site looks like? Can you adapt some of these features and ideas in your own code? Post a link and a brief summary of one idea that you got from looking at the source code for the article you selected to the Success Skills - Share it discussion.

  14. Blogs/Vlogs - Consider subscribing to the blogs or vlogs (video) of people or groups that regularly provide new and interesting information about a subject that interests you. Blogs/Vlogs are used by individuals, companies, colleges and organizations as a way to provide updates and news to "subscribers" - usually by email. But they are also viewable as web pages, so you don't have to subscribe to see the information.
    Pick two Blogs (or Vlogs) you find interesting and start reading them. Some that I like - Scientific American, Gizmodo.
    In the Blogs discussion, for one that you selected, post a link and a brief description and why you selected it.

  15. Themes - Popular blogging software includes WordPress and Weebly. WordPress is available as an "open source" application you can download and run on your own web server, or as a hosted service at WordPress.com. For these, the content of the site pages are stored separately from the format information by making extensive use of CSS functionality. A "theme" created with Cascading Style Sheets (CSS) can be selected and applied to the site content. Other sources such as Bootstrap sell "themes" (complete CSS stylesheets) as well.
    Look through the Weebly themes or WordPress themes that are provided. It is important to understand how powerful CSS is for determining the look and layout for a site. The pages for your site don't have to have all the formatting coded on each page.
    Select 2 examples of themes from the themes gallery. The content is the same - text, associated pictures, links and category information. What are the noticeable differences between the page displays? What layout features are important to you and the display of your content? Post links to the gallery pages for the themes you are comparing, and a brief description of the differences (2-3 sentences), and your preference to the Weebly / WordPress themes discussion. .

  16. Test drive - Twitter. Blogging in 140 characters. Read through the Newbie's guide to Twitter. Then search Twitter for some topics of interest. If you know hashtags or handles associated with topics and people, look them up. In the Test drive - Twitter discussion, post the contents of 2-3 tweets that are interesting along with 2-3 associated hashtags and a brief comment about your Twitter experience.

  17. Web Literacy - WRITE - Writing on the web enables one to build and create content to make meaning. Review the Web Literacy skills in the WRITE group. What is one thing that you aren't sure you understand? Look it up. In the Web Literacy - WRITE discussion, post a link to a resource where you found the answer.
