    <map> web page

    in HTML/XHTML

    Posted

    Yes, you are correct. Using an Image-map, you create 'hot-spots' which, when clicked, takes the user to the linked page.Biggest trouble is there is little, if any, content for the web Bots to index, so it won't boost your google page rank very much since images don't index very well.

    Centering Images

    in HTML/XHTML

    Posted

    img { margin-left:auto; margin-right:auto; text-align:center; padding:0;}The text-align is for some older non-standard compliant Browser to recognize the attempt to centre the picture. These older Browsers don't recognize the margin:auto. It works on Images, too.

    Choosing Text Formatting Tags

    in HTML/XHTML

    Posted

    I would use <b> and <i> for Bold and Italics, leaving <strong> and <em> to be used for other uses, like maybe when I wanted to make a piece of text special besides Bold or Italics. Perhaps a different colour or line height or various other text formatting.strong and em can be defined inside your css for the page. The default for them in most Browsers is bold and italics, but they don't need to stay that way.

    Help choosing a web project...

    The most common Forum Softwares are written using php as a means to add and retreive data from a Database, typically Mysql. I suppose that in order to write a Forum, you might need to learn some php and mysql.Also, might not hurt to post the course project requirements here so we could understand what you will be working against.

    php tables error

    in PHP

    Posted

    The file needs to be viewed through a Browser and there needs to be a php parser to handle the php requests. If you have a version of php installed on your machine, make sure it is running and have the browser set up to parse the page as a php page, not an html page.

    which DOCTYPE

    in JavaScript

    Posted

    You don't need one. The only thing that needs a DOCTYPE (To my knowledge) is XHTML. You can use one for HTML but it isn't required.
    You are correct. An HTML file does not "require" a DTD, but in order to have the Browsers play well with the html code, it is very highly reccomended that you use a DTD in order to avoid the Browser using "quirks" mode when it renders your page. A correct DTD will standardize the rule the Browser uses. A faulty DTD, or lacking a DTD, lets the Browser define its own rules about the rendering and you will lose any consistency between pages. In short, use any DTD you wish, but code to the DTD you have selected.As for javascript, there is not any single DTD which javascript requires, but the more demanding the DTD, the less likely that the html validators will approve of the code. The best way to "validate" an html file using javascript is to seperate the javscript into a seperate external file.

    IE7 Layout issue

    I don't have a copy of IE7 on this machine, but try this code and let me know if it works.

    I have combined the html and css into one file for ease of editting and posting here.

    Problem linking to external CSS file

    in CSS

    Posted

    From the information you provide, I would think that this is all that you should have in the css file:

    body {background-image:url('parishmagbackground.gif');background-color: yellow;}

    The html, head, style and body tags are for the html file only, and don't belong in the css file.

    Authentication and Security!

    And the code is where???I am guessing that there is a Header or something being sent to the browser and the parser is complaining that the headers have already been sent. NOTHING can be sent before the headers, not even a blank space.Post your code and let us have a look.

    IE Won't scroll page / image map is jacked up

    in HTML/XHTML

    Posted

    First thing to do is add a valid Document Type Declaration which forces the html page to be rendered in Standards Compliant Mode. With no DTD, the page is in Quirks Mode which is why the two Browsers are so different. The DTD won't fix everything, but it will be easier to fix if the page is in Standards Compliant Mode.

    change the tr dynamically

    in CSS

    Posted

    Here is a piece of code which reads information from a text data file and then echos it back out using the modulus (%) function to determine if the class = hi-lite is needed to change the background colour of the table row.

    <table>	 <tr class="hi_lite">		 <th>Date and Time</th>		 <th>Sender</th>		 <th>Email</th>		 <th>Message</th><?phpif ($show_IP){echo '<th>IP Address</th>';   };echo '</tr>';$row=0;while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {	if ($row % 2) { $data_string .= '<tr class="hi_lite"> ';	}	else  { $data_string .= '<tr> ';	}	 	if ($show_IP){$num = count($data);		   }				else {$num = (count($data) - 1 );					   };		   		 for ($c=0; $c < $num; $c++) {			 $data_string .= '<td> ' . $data[$c] . " </td>";			   };		$data_string .= '<tr> ' . "\r\n\t";		$row++;			 };		print $data_string;		$data_string = "";fclose($handle);?></table>
