VBScript rollover. Image swap

Windows : Internet Explorer 4.0+.

VBScript rollover, using image swap. Two examples: several ways of applying VBScript in a web page.

VBScript rollover

Example 1

VBScript rollover. Image swap

HTML / XHTML. Code:

<a href="#" onmouseover="onMouse_over()" onmouseout="onMouse_out()"><img src="out.gif" id="rollover" alt="" /></a>

VBScript. Code (<script> tag including):

<script type="text/vbscript">

Sub onMouse_over()

rollover.src='over.gif'

End Sub

Sub onMouse_out()

rollover.src='out.gif'

End Sub

</script>

Note: an external VBScript script file may also be used. The code itself is the same (without <script> tag pair, surely). The file is linked to page very much like a JavaScript file would be:

<script type="text/vbscript" src="vbscript.vbs"></script>

VBScript rollover

Example 2

VBScript rollover. Image swap

HTML / XHTML. Code:

<a href="#"><img src="out.gif" id="rollover2" alt="" /></a>

VBScript. Code (<script> tag including):

<script type="text/vbscript" event="OnMouseOver" for="rollover2">

rollover.src='over.gif'

</script>

<script type="text/vbscript" event="OnMouseOut" for="rollover2">

rollover.src='out.gif'

</script>

HTML centering

 

Centering the whole content of a web page in the viewable area of a browser by pure HTML - no CSS. A box to keep the content of the page is HTML centered horizontally and vertically - [ Open demo page ] HTML. Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>HTML centering</title> <meta http-equiv="Content-Type" content="text/html; charset=Windows-1252"> </head> <body bgcolor="#ffffff"> <table width="100%" height="100%" bgcolor="#a3ddc4"> <tr> <td align="center"> <table width="800" height="500" bgcolor="#ff6f6f"> <tr> <td>&nbsp;</td> </tr> </table> </td> </tr> </table> </body> </html> The outer HTML table makes the whole web browser viewable area, except margins, a HTML table and the whole area of this HTML table - a HTML table cell. The cell of the outer HTML table inherits the default value for valign attribute from its parent table row. And this row in its turn inherits the default value for valign attribute from the outer HTML table tbody - even if tbody tag is not used. And that value is middle. So a block of content inside the cell of the outer HTML table is centered vertically in web browser viewable are. Align="center" of the outer HTML table cell makes a block of content inside it centered horizontally in web browser viewable are. The inner table, the one inside of the outer HTML table cell makes up a box of a given size. Or there may be no set height or no set width or both. Then the size of the box is to adjust to accommodate the content, whatever its dimensions are. If the width or height or both of the box results to be larger than web browser viewable area, then it still ends up to be centered. Since HTML centering is the oldest method to center content horizontally and vertically, it works well not just in older web browsers, but in ones that can be described as downright ancient. Like adding one more HTML tag ( <center></center> ) around the outer table makes it funcion as deep as Internet Explorer 3 : [ Open demo page ] Download Internet Explorer 3: a pack, containing 3.0, 4.01, 5.01, 5.5, 6.0 versions of Internet Explorer HTML.
