HTML Mark-up codes given in these classes have generally been consistent with HTML version 3.2. At the time of this writing, HTML version 4.0 has been approved as a standard by the W3C (World Wide Web Consortium) but its new elements and attributes have only been incorporated into the most up-to-date browsers and we recommend using these only when their use is not critical to the readability of your pages.
Frames have not been addressed in these classes because their use is considered to be marginally desirable. Frames present a number of problems including the potential to be a security hazard on a web site.
Images present a challenge to most beginning web spinners. Images may only be taken from other authors' web pages when those authors give specific permission. Fortunately there are a number of sites where simple icons, buttons and bars are placed there for you to take.
When using image maps remember that many people browse with their image loading switched OFF. Therefore you should have text links available for the same links embedded in your images.
FORMSThe information given here about the construction of forms is relevant for all web pages except for the reference to the server-side CGI script (Common Gateway Interface program or batch file generally written in C, Pascal or Perl). CGI scripts are resident on the web server and are responsible for doing such things as making forms work.
If you are not a DCN subscriber you will need to contact your Internet Service Provider to find out how to refer on your web page to their server-side file for your forms.
Forms will not work on your hard drive. In order to check them you must upload them to your public_html directory on your Internet Service Provider's web server.
The form laid out on the following page includes a number of form elements and attributes but you will almost certainly need to "view" other authors' forms and read up about forms in an HTML reference in order to be able to construct a form in exactly the manner in which you need it to perform.
FORM STRUCTURE: - an exercise (View this form)
A form element is enclosed in a <FORM> </FORM> paired tag.
<FORM METHOD="post" ACTION="script.url">
The "script.url" is the location on your ISP's web server where the CGI script that will translate your form resides.
