    Assignment Prompt & Instructions

    [>Java homework help](https://www.sweetstudy.com/fields/computer-science-java)

    ## **Overview**

    This assignment builds on your work for Week 1. You will be adding to your index page and creating two more pages for your site. You will also be creating the navigation links, external links, and adding images to your pages. The focus is just on HTML, so do not include any CSS or style tags in the pages (that will come next week).

    **AI Use**

    For this assignment, you are welcome to use AI chatbots to elicit explanations and examples of the various semantic and text markup HTML tags covered in the reading, but you should not use the AI to generate code, nor should you copy and paste code into your assignment from an AI or other outside resource. You are also welcome to use an AI chatbot to address validation errors and other problems with the code, but you must enter any changes yourself (again, no copying and pasting).

    **No CSS Styling**

    This week's assignment is working with plain HTML. You will start using CSS in the next assignment, but do not use it for this week's work.

    ## **Preparation**

    – On your desktop (or other location that you can find easily), create an empty folder named IT3240_Week_2.
    – Copy your index.html file from week 1 and add it to the new folder (along with any images used on the index page). Open this folder in Visual Studio Code.

    ## **Editing index.html and Adding New Pages**

    1. Add <main> and <footer> tags to your index page with the correctly paired closing tags and add relevant content to these sections (you should already have a <header>). The presence of these semantic tags may not alter the appearance of the page this week, but they will play a role when you start styling your pages and working on layout using CSS for future assignments.
    2. Add at least three HTML comments to identify the page in the code and document parts of the page.
    3. Add a <nav>…</nav> section to your index page with links to your index.html and the about.html and contact.html pages that you will be creating below.
    4. Use at least five semantic and text markup tags from those discussed in the reading (besides those used already) to mark up the text of the index page (adding additional text as needed). Be sure are text is contained in <p>…</p> or other appropriate text/semantic tags.
    5. Using your index.html as model for the HTML structure tags, create the "about" page (about.html) with a title like "About Us" or "About [organization name]."
    – Replace the content of the page with content (and HTML markup) for the "about" page.
    – Include the <nav>…</nav> section from the HTML page with the same links.
    – Use semantic tags and text markup tags appropriate for the content of the page.
    – Include at least one list (unordered, ordered, or description list on the "about" page).
    – Add at least one image that is unique to the "about" page.
    – Include at least 50 words of content specific to the "about" page.
    – Insert at least three HTML comments to identify and document the page.
    6. Again, using the index.html as a model for the HTML structure tags, create the "contact" page (contact.html).
    – Include content for the page with appropriate HTML tags.
    – The page should have the same site navigation links as the other pages.
    – Include at least two external links (hyperlinks or email addresses).
    – Include at 50 words of text to the page (the contact information counts as content).
    – Add at least three HTML comments to identify and document the page.

    ## **Verifying Your Work**

    1. Test them in two different browsers to confirm that they work as expected. In a Word document, state which browsers you tested the pages in. You _do not_ need screenshots of the pages displaying in the browsers.
    2. Go to the Nu HTML Checker tool at [validator.nu](https://capella.alma.exlibrisgroup.com/leganto/public/01CAPELLA_INST/lists/5381565470006731?auth=SAML&section=5381567610006731) to check the HTML for all three pages. In the "Check by" dropdown menu, select "file upload." Then, click the File Upload button to upload the .html file to be validated. After the file has been uploaded, click the Check button. Repeat the process for each HTML file.
    3. Fix any errors noted by the tool and correct the causes of any warnings.
    4. You are welcome to use an AI chatbot to assist with understanding the problems and to suggest corrections, but you need to decide on the steps to be taken, and you must type in the code yourself. Do not copy and paste code from the chatbot or allow the AI to modify your code. Re-check the .html file as needed until all issues have been addressed.
    5. Take a screenshot of the Nu HTML Checker results for each page that was edited showing successful validation and add it to the Word document with the statement of which browsers you tested the page in.

    ## **Submission Requirements**

    – Add the Word document to the folder containing the three .html files and the image files.
    – Please do not include any extra files in your submission.
    – Compress the folder and submit the zip file as an attachment to your submission.

    ## **Competencies Measured**

    By successfully completing this assignment, you will demonstrate your proficiency in the following course competencies and rubric criteria:

    – Competency 1: Author well-structured, standards-compliant HTML
    – Uses semantic and text markup tags.
    – Creates "about" and "contact" pages.
    – Tests in 2 browsers.
    – Validates HTML and fixes errors.
    – Competency 2: Style web page content using current CSS.
    – Adds navigation section with links.

    Assignment Prompt & Instructions

    ## **Overview**

    For this assignment, you will create an external, common CSS stylesheet to give you pages a consistent style (typography, colors, margins, etc.). The focus is on styling the color scheme and typography. Upcoming assignments will make use of CSS page layout techniques, so steer clear of CSS declarations such as display: flex; and display: grid.

    ## **Preparation**

    – Take some time to plan a color scheme for your site. The following guidelines will help you:
    – The color pallet should be limited to three to five main colors. Black, white, and gray are colors, too.
    – Maintain good contrast so the text of the page is readable.
    – Be consistent in the use of colors for parts of the page (use the same heading colors, all buttons should be the same color, apply the same colors for the navigation, etc.).
    – You may want to use Google Fonts for you site so that all users see the same font, regardless of the platform. Go to [Google Fonts](https://capella.alma.exlibrisgroup.com/leganto/public/01CAPELLA_INST/lists/5381565470006731?auth=SAML&section=5695222620006731) and select your font(s). It is fine to use more decorative fonts for headlines but choose plainer fonts for the text of the page. For best results, do not use more than two fonts.
    – On your desktop (or other location that you can find easily), create an empty folder named IT3240_Week_3. Copy your files from the Week 2 assignment (including images). Open this folder in Visual Studio Code.

    ## **Adding the CSS**

    1. Add a .css file to your site's directory with the file name style.css.
    2. Add appropriate <link> tags to the HTML files so that all pages use the same CSS. All CSS rules will go in this file (do not include any style rules or <style> tags in the HTML (other than the tags required to use Google fonts, if you choose to use them).
    3. Using a combination of selectors for tags, classes, and ids, add at least ten CSS style rules to the .css file. When using class and id selectors, you will need to add the corresponding class and id attributes to the HTML tags.
    4. Aim for a consistent look and feel for all pages. There may occasionally be a style that is specific to an element on a particular page, but avoid writing separate styles for the index page, the about page, and the contact page.
    5. Only use <div>…</div> and <span>…</span> tags in the HTML when there isn't a semantic or text element HTML tag that applies.
    6. Use relative units when specifying most sizes in CSS to produce a more responsive design. Sizes in pixels are often too rigid to work well at different resolutions.
    7. It is important to document the CSS with comments. Include at least one comment for each CSS style rule.

    ## **Verifying Your Work**

    1. After you are done working on your pages, test them in two different browsers to confirm they work as expected. In a Word document, state which browsers you tested the pages in. You _do not_ need screenshots of the pages displaying in the browsers.
    2. Any HTML files where you made changes, need to be revalidated. Go to the Nu HTML Checker tool [validator.nu](https://capella.alma.exlibrisgroup.com/leganto/public/01CAPELLA_INST/lists/5381565470006731?auth=SAML&section=5381567610006731) to verify the HTML. In the "Check by" dropdown menu, select "file upload." Then, click the File Upload button to upload the .html file to be validated. After the file has been uploaded, click the Check button. Repeat the process for each HTML file with changes.
    3. Fix any errors noted by the tool and correct the causes of any warnings.
    4. Validate the CSS file using the [CSS Validation Service](https://capella.alma.exlibrisgroup.com/leganto/public/01CAPELLA_INST/citation/5381591580006731?auth=SAML). The process is essentially the same as the HTML validation (use the "by File Upload" option). Correct any errors in the CSS identified by the validator.
    5. You are welcome to use an AI chatbot to assist with understanding the problems and to suggest corrections, but you need to decide on the corrections to be made, and you must type in the code yourself. Do not copy and paste code from the chatbot or allow the AI to modify your code. Re-check the edited .html files and revised .css file as needed until all issues have been addressed.
    6. Take a screenshot of the Nu HTML Checker results for each page showing successful validation and add it to the Word document with the statement of which browsers you tested the page in. Add the CSS validation screenshot showing successful checking of the CSS to the same document.
