You may have to include a php script to do this work.. here is a php example which is very easy....Just change your form.html to form.php and then put this code in between your head tag <?php if(isset($_POST['ok'])) { mail($_POST['mailTo'],$_POST['subject'],$_POST['message']); } ?> And make your form like this: <form method="POST">Reciepent's Email:<input type="text" name="mailTo" size="30"><br>Subject:<input type="text" name="subject" size=50><br>Message:<textarea rows="10" cols="30" name="message"></textarea><br><input type="submit" name="ok" value="Send"></form> you can put an alert inside the form tag.

You may have to change you file name from index.html to index.shtml then you can include your menu.html page in any file....if you dont want to change the extension of file then use the javascript...1. Create an external javascript file on notepad by typing.. document.write("<a href=your-location>Menu1</a><br>");document.write("<a href=your-location>Menu2</a><br>");document.write("<a href=your-location>Menu3</a><br>");document.write("<a href=your-location>Menu4</a><br>"); 2. Now save it as your-file-name.js3. Include it in html page anywhere by typing <script type=text/javascript src="your-file-name.js"></script> That is a sample.. you can make changes to script.

Okey i tellI have a list of articles in database.. suppose i have 50 (id = 1 to 50)Now every week i want to display 10 unique article links on my main page.....

<span style="width: 150; height: 50; font-size: 20px; font-family: verdana; color: #ff00cc; filter: dropshadow(Color=#00ff00, OffX=2, OffY=2, positive=2)">Dropshadow</span> Use your settings or read the other effect tutorial at this page Creating Text Effects using CSS

GET and POST both are used in forms to submit informations..let suppose you have a form[code]<form action=&#34;index.php&#34; method=&#34;POST&#34;><input type=&#34;text&#34; name=txtUser><input type=&#34;submit&#34; value=&#34;Submit&#34;></form>[/code]Now when you submit the form the address bar will show only the addess of index.php .. all the information (txtUser) will be passed with headers.. but now shown in Browser's address bar..It will as like following[b]http://www......./index.php[/b]But if you use the GET method instead of POST then after submitting you will notice that address bar will show [b]http://www......./index.php?txtUser=[color="blue"]value[/color][/b]where value is that which is wrriten in text box..I hope you have understand the difference now :)

Do you want to split the page by using frames or table??The code for the table is below <html><head><title> Page title</title></head><body><table width="75%" align="center" border="1"><tr><td width="100%" colspan="3"> This is the heading or the top Row <br><br></td></tr><tr><td width="20%"> The left Column<br><br><br><br><br></td><td width="60%"> The center Column</td><td width="20%"> The right Column </td></tr></table></body></html> You can specify the height of table. But if you use the CSS the code can be reduced.

use for a single space wherever you want to put a space.
