DHTML means the web page or web application uses JavaScript and HTML DOM (Document Object Model) and possibly CSS.

A programmer can create dynamic web pages using these technologies. For example when I move the mouse over a image link, I can change the image.

ASP and ASP.NET pages are converted to HTML by a server.

Test them.

To enable dynamic loading of extensions, set enable_dl option in php.ini to 1

A snippet is a piece of code that has already been written for you by other developers. To save time and effort writing your own commands/functions, you can use code-snippets made by others to make your job easier.

The <ol> tag creates an ordered (i.e. numbered) list in HTML.

The term for logging in at a website is "log on to" or "log onto" (there is a slight semantic difference that is practically never observed).

Place this code on your website: <SCRIPT TYPE="text/javascript">

var message="Protected image can not be saved.";

function click(e) {

if (document.all) {

if (event.button 3) {

alert(message);

return false;

}

}

}

if (document.layers) {

document.captureEvents(Event.MOUSEDOWN);

}

document.onmousedown=click;

</SCRIPT>

It is a matter of personal preference. Each one comes with its plus and minus points. You need to choose according to your requirements, skills and preference.

You can counter the styles declared for the general element type. For example, if the earlier CSS declared "background-color: #FF0000;" for all "div" elements, but you want a specific "div" tag to have a different background color, you can add "background-color: #00FF00;" as a declaration to that specific "div" tag. A live example: ----

Add float:left; to the style element of the image. All following text will flow around the image on the right side.

Of course there not why did you think they?

The purpose of form validation is to ensure that valid data is input provided by the user of the web page.

If the data provided in the form is incorrect and used without proper validation we may end up using inconsistent data that would be of no use to us.

Let me explain with an example. Let us say you are designing a page where the user enters his details to register to use your site, you need to ensure that he enters a valid email address, telephone number etc. Let us say he enters xxyydsdf in the email text field and abcdedf in the phone number field, your form should be in a position to find it out and tell the user that the data he entered is wrong. Also our code should stop him submitting the information.

Else, on some day when the user has used the website for some malicious purpose and you need his contact information which the law enforcement authorities request, if you provide xxyydsdf as email and abcdedf as phone number it would be the worst thing that can happen to you.

It's a thing that varies.

1. A web service is a service that is available for use over the internet. "Servers" are called such because they provide "services." Don't be confused by someone pointing at a computer and calling it a "server", strictly speaking this is incorrect even though it is a vernacular used nearly everywhere. What the person means is that computer runs server software that provides services over a network.
2. As for who writes it, there is no definitive answer other than "the programmer/s". As there are far too many web services and programmers of them out there to discuss.
3. Similarly for how it works, it depends on the specific service you want to discuss and since there isn't one named there are too many out there to mention.

End tags on void elements must not be used. A void element is any element that cannot have any content. The HTML 4,01/XHTML 1.0 Strict void elements are: <area>, <base>, <br>, <col>, <hr>, <img>, <input>, <link>, <meta>, and <param>. HTML5 also adds <command>, <keygen>, and <source>.

In XHTML, all void elements must be self-closing. For example:

<input type="submit" value="OK" />

In HTML 4.01, use the following instead:

<input type="submit" value="OK">

Both forms can be used in HTML5, however self-closing void elements are preferred.

The following must not be used:

<input type="submit" value="OK"></input>

Elements that normally have content (i.e., all non-void elements) must have an end tag even if they have no content.

<a id="myanchor"></a>

The following must not be used:

<a id="myanchor" /a>

HTML 4.01 allows certain non-void elements to be used without an end tag (the end tag is implied). For example, the <p> element can be used without a corresponding </p> tag:

<p>This is a paragraph.

<p>This is another paragraph.

However, do not rely on this.

Because JSPs are designed to take care of the View part of the MVC design patter and not the controller. You can have little or some amount of logic in it, but it is not designed/created with the idea of controlling the flow of control in a J2EE application.

The Value Object pattern provides the best way to exchange data across tiers or system boundaries, especially when there is network communication involved. This is a pattern that solves performance issues around network latency

This pattern is an object that encapsulates a set of values that is moved across the boundary so that attempts to get the values of those attributes are local calls.
