Script tag can be inside the head or body tag of the HTML code. This tag is executed when the browser reaches that part of the document.
        <h2>HTML Script Tag Example</h2>    
           var x = 5;
           var y = 6;
           var result = x + y;
         alert("X + Y is equal to " + result);

Document Style Semantics and Specification Language is an international standard, an expression language, a styling language for associating processing (formatting and transformation) with SGML documents, for example XML.
Double or single quotes in URLs are optional. The tree following examples are equally valid:
body {background: url(imgs/ftl_logo.png) blue}
body {background: url("imgs/ftl_logo.png") blue}
body {background: url('imgs/ftl_logo.png') blue}
It is relative to the parent element's font-size. For example, if the style sheet says:
H1 {font-size: 20pt;}
SUP {font-size: 80%;}
Yes. If more than one declaration is attached to a selector they must appear in a semi colon separated list, e.g.;
Selector {declaration1; declaration2}
P {background: white; color: black}
echnically, since HTML is an SGML application, HTML uses SGML comment syntax. However, the full syntax is complex, and browsers don't support it in its entirety anyway. Therefore, use the following simplified rule to create HTML comments that both have valid syntax and work in browsers:
An HTML comment begins with "<!--", ends with "-->", and does not contain "--" or ">" anywhere in the comment. 
The following are examples of HTML comments:
* <!-- This is a comment. -->
* <!-- This is another comment,
and it continues onto a second line. -->
* <!---->
HTML has no mechanism to control this. However, with CSS, you can set the margin-bottom of the form to 0.

For example : 
<form style="margin-bottom:0;" action=...>
You can also use a CSS style sheet to affect all the forms on a page:
form { margin-bottom: 0 ; }
Just use the image as the link content, like this:
<a href=...><img src=... alt=...></a>
