Answer 1

This link should help you. You will find the syntax for gradients there.
It's this one for all the major browsers:
background-color: #444444;
background-image: -webkit-gradient(linear, left top, left bottom, from(#444444), to(#999999));
background-image: -webkit-linear-gradient(top, #444444, #999999);
background-image: -moz-linear-gradient(top, #444444, #999999);
background-image: -ms-linear-gradient(top, #444444, #999999);
background-image: -o-linear-gradient(top, #444444, #999999);
background-image: linear-gradient(to bottom, #444444, #999999);
filter: progid:DXImageTransform.Microsoft.gradient(startColorStr='#444444', EndColorStr='#999999');
…while #444444 is the color at top of the gradient and #999999 the gradient-color at the bottom.
The different "vendor-prefixes" ensure that the gradient works in different browsers as the 'default'-syntax is not supported by every browser by now.
The filter-property will make the gradient work in Internet Explorer 8 and below. But this has some drawbacks (performance aso…). Just use it if really necessary.
Edit: The syntax for linear-gradient changed. The spec'd syntax:
background-image: linear-gradient(to bottom, #444444, #999999);
I've changed this above too, so everyone can just copy this.

Without seeing the colors you are working with, you want to do something like this
.class{
background: -webkit-gradient(linear, left top, left bottom, from(#fff), to(#000));
background: -moz-linear-gradient(top, #fff, #000);
}

CSS gradients are cool stuff. But you have one problem. When you are used background gradients in ie9. You can not used border radius are other CSS3. The background filter propertiy for ie is suck. I have a better solution for this. That fix the problem in ie9.
With this tool you create a gradient: http://www.colorzilla.com/gradient-editor/
And with this tool you create a SVG for ie9: http://ie.microsoft.com/testdrive/graphics/svggradientbackgroundmaker/default.html
Now we have this code:
background-image:url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxMDAlIiBoZWlnaHQ9IjEwMCUiIHZpZXdCb3g9IjAgMCAxIDEiIHByZXNlcnZlQXNwZWN0UmF0aW89Im5vbmUiPgo8bGluZWFyR3JhZGllbnQgaWQ9Imc1OCIgZ3JhZGllbnRVbml0cz0idXNlclNwYWNlT25Vc2UiIHgxPSIwJSIgeTE9IjAlIiB4Mj0iMTAwJSIgeTI9IjEwMCUiPgo8c3RvcCBzdG9wLWNvbG9yPSIjNDQ0NDQ0IiBvZmZzZXQ9IjAiLz48c3RvcCBzdG9wLWNvbG9yPSIjOTk5OTk5IiBvZmZzZXQ9IjEiLz4KPC9saW5lYXJHcmFkaWVudD4KPHJlY3QgeD0iMCIgeT0iMCIgd2lkdGg9IjEiIGhlaWdodD0iMSIgZmlsbD0idXJsKCNnNTgpIiAvPgo8L3N2Zz4=);
