I am using Amaya to edit html for the classes I teach. I have been trying to insert iframe tags into the html to display YouTube videos. I can successfully do this and save the results, but only if I do not return to the GUI screen and make any changes there. If I do make changes on the GUI screen, all the iframe tags are deleted. Here's a simplified version I've been using for testing:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1">
<title>iframe test</title>
</head>
<body>
<p>some text</p>
<iframe src="http://www.w3schools.com"></iframe>
</body>
</html>
This code runs fine and shows the W3 Schools window. But if I use Amaya to make changes in the GUI, by, say, changing "some text" to "more text," the line <iframe src="http://www.w3schools.com"></iframe> is stripped out.
Can anyone tell me why Amaya does this, or how I can get Amaya to keep from stripping out my iframes?
