Webfont Smoothing and Antialiasing in Firefox and Opera

Question

I have custom-made web fonts used on my site. To style my rendering output, I used the following code:

//-webkit-text         


        

Answer 1

... in the body tag and these from the content and the typeface looks better in general...

body, html {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
text-rendering: optimizeLegibility;
text-rendering: geometricPrecision;
font-smooth: always;

font-smoothing: antialiased;
-moz-font-smoothing: antialiased;
-webkit-font-smoothing: antialiased;
-webkit-font-smoothing: subpixel-antialiased;
}


#content {
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;

}

Answer 2

As Opera is powered by Blink since Version 15.0 -webkit-font-smoothing: antialiased does also work on Opera.

Firefox has finally added a property to enable grayscaled antialiasing. After a long discussion it will be available in Version 25 with another syntax, which points out that this property only works on OS X.

-moz-osx-font-smoothing: grayscale;

This should fix blurry icon fonts or light text on dark backgrounds.

.font-smoothing {
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
}

You may read my post about font rendering on OSX which includes a Sass mixin to handle both properties.

Answer 3

Case: Light text with jaggy web font on dark background Firefox (v35)/Windows
Example: Google Web Font Ruda

Surprising solution -
adding following property to the applied selectors:

selector {
    text-shadow: 0 0 0;
}

Actually, result is the same just with text-shadow: 0 0;, but I like to explicitly set blur-radius.

It's not an universal solution, but might help in some cases. Moreover I haven't experienced (also not thoroughly tested) negative performance impacts of this solution so far.

Answer 4

After running into the issue, I found out that my WOFF file was not done properly, I sent a new TTF to FontSquirrel which gave me a proper WOFF that was smooth in Firefox without adding any extra CSS to it.

Answer 5

When the color of text is dark, in Safari and Chrome, I have better result with the text-stroke css property.

-webkit-text-stroke: 0.5px #000;

Answer 6

Well, Firefox does not support something like that.

In the reference page from Mozilla specifies font-smooth as CSS property controls the application of anti-aliasing when fonts are rendered, but this property has been removed from this specification and is currently not on the standard track.

This property is only supported in Webkit browsers.
