Mailto Forms and Using Color Mailto Forms and Using Color: Using The Mailto URL With Forms One of the more difficult aspects of forms is creating the server-side scripts that process the form data. This can be a daunting task for non-programmers and impossible for those webmasters who cannot create server-side scripts at all. Fortunately, all is not lost. It is possible to create forms and retrieve user-supplied data without writing or installing server-side processing scripts. The trick is to use the mailto URL to retrieve the form data. Normally, the mailto URL is used in a conventional link. When clicked by the user, the browser opens some sort of mail composition window, collects a message, and sends it to the address specified in the URL. When used as the action attribute of a form, the mailto URL instead mails the form data to the address in the URL. By setting this address to yourself, you can receive form data as conventional email messages. Before showing how all this works, keep in mind several caveats: · This does not work with Internet Explorer 3.0 · The data is sent to you in an encoded form (but can be converted, as I discuss below) · Conventional user feedback is not possible after the form is processed Given these warnings, let's go ahead and use this idea anyway! A Simple Example Here is a simple form, with a mailto URL as the form action: <form method=POST action="mailto:[email protected]" enctype="text/plain"> Name: <input type=text name="Name" size=40><br> Phone:<input type=text name="Phone" size=10 maxlength=10><br> Category:<input type=radio name="Category" value="Boats"> Boats <input type=radio name="Category" value="Cars"> Cars <input type=radio name="Category" value="Trucks"> Trucks <input type=radio name="Category" value="Planes"> Planes Description:<textarea name="Description" rows=6 cols=40></textarea> <input type=submit> </form> In case you are wondering, the resulting form looks like this: Name: Phone: Category: Boats Cars Trucks Planes Description: Submit Query Notice that this is a normal form, except that I used method=POST, enctype="text/plain", and set the action attribute to a mailto URL. Don't actually submit this form; you'll just send an empty message to my server. What You Get When a user submits the form, the form data is presented in a fairly readable format. For example, if I typed in my name and phone number, selected "Cars", and type a few lines of text into the text area in the form, the data that gets mailed to me looks like this: Name=Chuck Musciano Phone=123-4567 Category=Cars Description=this is a textarea tag As far as I can tell, if a browser doesn't support text/plain as the encoding, it will use the default encoding instead. This looks something like this: Name=Chuck+Musciano&Phone=123- 4567&Category=Cars&Description=This+is+a%0D%0Amulti-line%0D%0Ainput+field Bleah. At first, this seems totally useless. But a few simple substitutions and things will be looking much better. Just replace all the plus characters ("+") with spaces, and the ampersands ("&") with carriage returns: Name=Chuck Musciano Phone=123-4567 Category=Cars Description=This is a%0D%0Amulti-line%0D%0Ainput field The final conversion is to replace any %0D%0A sequences in your multiline input fields with line breaks. The bottom line: use enctype="text/plain" to make some, if not all, of your form results easier to read. Final Thoughts One drawback to the whole mailto form idea is that there is no way to give a user feedback that the form was correctly sent. Only use this trick when there is no other alternative. If you can make things work with a regular form CGI script, by all means, do it. Finally, remember that this only works with most browsers. Some older browsers may refuse to honor the mailto URL and not handle your form correctly. Using Hexadecimal Color Codes The Hexadecimal Color Codes are used for many things in HTML. For Page Backgrounds: <body bgcolor="#hexdec"> For Text Colors: <font color="#hexdec"> For Page-Wide Link and Text Colors: <body text="#hexdec" link="#hexdec" vlink="#hexdec" alink="#hexdec"> (where text is text color, link is non-visited link color, vlink is already-visited link color, and alink is the color a link turns at the second it is clicked) There are 16.7 million different colors in the hexadecimal color system. #000000 is black, and #FFFFFF is white. Each of the 6 digits in the hexadecimal code is broken into 3 seperate groups... · #XXxxxx - Red Color Value · #xxXXxx - Green Color Value · #xxxxXX - Blue Color Value Each digit is a value from 0 to F, in the hexadecimal system. The hexadecimal color system counts by 0 1 2 3 4 5 6 7 8 9 A B C D E F, with 0 being null value, and F being highest value. So if the first two digits (red values) are full (FF) and the other four are null (00) the color will be red. #FF0000 - AaBbCcDdEeFf1234567890 Background #FF0000 If the first two are null (00), the third and fourth digit (green value) are full (FF), and the fifth and sixth digit are null (00), the color will be green. #00FF00 - AaBbCcDdEeFf1234567890 Background #00FF00 If the first four digits are null (00), and the fifth and sixth digit (blue value) are full (FF), the color will be blue. #0000FF - AaBbCcDdEeFf1234567890 Background #0000FF Here is an example of the different shades of colors between black and white. #000000 - AaBbCcDdEeFf1234567890 Background #000000 #111111 - AaBbCcDdEeFf1234567890 Background #111111 #222222 - AaBbCcDdEeFf1234567890 Background #222222 #333333 - AaBbCcDdEeFf1234567890 Background #333333 #444444 - AaBbCcDdEeFf1234567890 Background #444444 #555555 - AaBbCcDdEeFf1234567890 Background #555555 #666666 - AaBbCcDdEeFf1234567890 Background #666666 #777777 - AaBbCcDdEeFf1234567890 Background #777777 #888888 - AaBbCcDdEeFf1234567890 Background #888888 #999999 - AaBbCcDdEeFf1234567890 Background #999999 #AAAAAA - AaBbCcDdEeFf1234567890 Background #AAAAAA #BBBBBB - AaBbCcDdEeFf1234567890 Background #BBBBBB #CCCCCC - AaBbCcDdEeFf1234567890 Background #CCCCCC #DDDDDD - AaBbCcDdEeFf1234567890 Background #DDDDDD #EEEEEE - AaBbCcDdEeFf1234567890 Background #EEEEEE #FFFFFF - AaBbCcDdEeFf1234567890 Background #FFFFFF Here are some examples of mixed colors... #FFFF00 - AaBbCcDdEeFf1234567890 Background #FFFF00 #00FFFF - AaBbCcDdEeFf1234567890 Background #00FFFF #FF00FF - AaBbCcDdEeFf1234567890 Background #FF00FF #ABCDEF - AaBbCcDdEeFf1234567890 Background #ABCDEF #FEDCBA - AaBbCcDdEeFf1234567890 Background #FEDCBA #A1F4BB - AaBbCcDdEeFf1234567890 Background #A1F4BB Try mixing your own colors in your web pages until you find one you like. .

  • How the Internet Works: DNS Activity Unit 3
    (http://csmatters.org) 3 - 5 0b11 - 0b101 How the Internet Works: DNS Activity Unit 3. Information and the Internet Revision Date: Jan 04, 2020 Duration: 2 50-minute sessions Lesson Summary Pre-lesson Preparation This lesson will require some room setup or prep for best delivery of instruction. Some of the setup should have been done in the previous lesson. Summary In this lesson, students will expand their knowledge of how the Domain Name System (DNS) works by acting as a class to simulate the use of DNS to retrieve web pages. Once the simulation is functioning students enhance its efficiency through the use of caching. Poison the DNS cache by adding false DNS replies (DNS poisoning). Students discuss with their groups how DNS works and how it supports Internet growth. Then they explain in their journals how: DNS works Caching is both a benefit and a security risk. DNS supports Internet growth. In this lesson, students will expand their knowledge of how DNS works by acting out a simulation of DNS in action and using it to retrieve web pages. This is a two-session lesson. The first session is for students to get the simulation functioning, with the teacher serving as director. As students realize they need to "fix" their implementation of the simulation (modify their scripts), they record the insights in their journals. In Session Two, students take on different roles and conduct a dress rehearsal that is entirely student-led. Teachers then introduce DNS caching and DNS poisoning. Once the simulation is functioning, students will address both increased efficiency due to DNS caching, and cybersecurity concerns associated with DNS.

  • <A Href=“ to Yahoo!</A> Hyperlinks Can “Link” To
    Hyperlinks can “link” to: Other web pages Images Files Places in the same document E-mail address A hyperlink is a word, phrase, or image that you can click on to jump to a new document or a new section within the current document. Hyperlinks are found in nearly all Web pages, allowing users to click their way from page to page. Text hyperlinks are often blue and underlined (that’s the default), but can be styled to be a different color. When you move the cursor over a hyperlink, whether it is text or an image, the arrow should change to a small hand pointing at the link. When you click it, a new page will open or the browser will jump to a place in the current page. After a hyperlink is clicked, it changes to a “visited” link and is purple by default. Paths There are two types of paths in HTML, known as relative paths and absolute paths. An absolute path contains the full URL of the item being referenced (starting with the http:// part). A relative path contains directions to the item relative to the HTML page. If it is in the same folder, it’s just the filename. This path will always be in quotation marks in the HTML tag. Anchor Tags The HTML tag used to create a hyperlink is an anchor tag, which is simply an A. However, an anchor tag can’t do anything on its own. You must also specific a hyperlink reference (where it is linking to) and the words (or image) that will be clicked on to take you there.
