‘Smooth fonts’ are calculated mostly by the browser and operating system. Which means you’ll probably only get the look you want by using an image or messing with some CSS ‘text-shadow’ to give the smooth illusion.
I think this will help you now and in your future works.
Open photoshop (or similar software) and open image panel. Select “L” radio button. Now add the background color of your text in color code field. Now select a contrasting color from vertical color bar. Then add a border with a color in between both of these colors (back ground color and text color) again from the vertical color bar.
Eg: If backgrund color is #ccc , then text color should be #333 and text-shadow color should be #666. (#ccc < #666 < #333)
Now it may look better.
