En iFrame er præcis som en "rigtig" frame, hvis du kender til det. Dens indholds udseende er bestemt af den side der indlæses i den, i dit tilfælde texttilforside.htm. Der hvor du skriver Røv skal der ikke stå noget, eller det er i hvert fald ikke meningen. Den tekst vil kun blive vist i en browser der ikke understøtter iframes.
Ang trqansparency, så har jeg ikke selv prøvet det, men se her:
Using Transparency with Inline Floating Frames
Although Internet Explorer has supported transparent elements since Internet Explorer 4.0, only Internet Explorer 5.5 supports transparent content with inline floating frames.
The following conditions must be met to define transparent content for inline floating frames.
The ALLOWTRANSPARENCY attribute, used with the IFRAME element, must be set to true.
In the IFRAME content source document, the background-color or BGCOLOR attribute of the BODY element must be set to transparent.
Note The BGCOLOR attribute can be applied to the BODY element, but it is deprecated as of HTML 4.0. It is recommended that you use the background-color attribute instead.
The following example shows how to apply the background-color attribute to the IFRAME content source file.
<HTML>
<BODY STYLE="background-color:transparent">
<P>Transparent.
</BODY>
</HTML>
The following example shows how the IFRAME element is written for transparent content.
<IFRAME NAME="Frame1" SRC="frame.htm" ALLOWTRANSPARENCY="true">
</IFRAME>
