To remove or hide default IE vertical scrollbar is easy. By default, IE displays vertical scrollbar even though the content fit nicely in the window without exceeding the viewport height. You can use CSS overflow:auto to show it only when you need it and hide it when there is no need for it.

html {
	overflow: auto;
}

Hope this helps.

In Firefox and Safari, by default, the iframe background is set to transparent, but in IE, it doesn’t. To make iframe background transparent in IE6 requires setting iframe attributes and background color CSS.

/* in the iframe element */
<iframe src="content.html" allowTransparency="true">
</iframe>

/* in the iframe docuement, in this case content.html */
body {
	background-color:transparent;
}

To remove the scrollbar appear at the right of the form textarea is easy. The default scrollbar can be hidden with a simple line of CSS. Below is how you can do it:

<style type="text/css">
textarea {
    overflow:auto;
}
</style>

Hope this helps! :)

CSS has a overflow property, if you set overflow to auto, the horizontal and vertical overflow may both come out even there is only vertical overflow.

To hide horizontal overflow, you need to use a CSS hack, be aware that this is not valid CSS, but it works in IE6 and above, Firefox and many major browsers.

You can use the CSS below to set horizontal overflow as hidden:

div {
    overflow-x: hidden;
}
