As I said in the previouse post (http://webprogram4beginners.blogspot.com/2011/01/how-to-design-php-website-by-help-of.html) we don't need to deal with HTML directly , but it's good to know some of the HTML tags.
<html> codes </html>
this tag shows the begin and end of the html codes.
-------------------------------------------
<br>
the browser jumps to the next line when it reaches to this tag.
------------------------------------------
<a href="an other web page"> the text to become link </a>
This tag shows a hyperlink for example:
<a href="main.php"> first page </a>
By this code , the browser shows the words "first page" as a link and if the user click on it the browser will redirect the address bar to "main.php" page.
-----------------------------------------
<img border="border of the image" src="the location of an image file(it can be a location on the web)" width="width of image" height="hight of image on the screen">
This tag shows an image on the screen , for example:
<img border="0" src="images_1/Image1509.jpg" width="120" height="160">
This code shows Image1509.jpg file from image_1 folder on the server.
