Font weight turns lighter on Mac/Safari


Answers

try both

{-webkit-font-smoothing: subpixel-antialiased;
-webkit-text-stroke:1px transparent;}
Question

On my last website, the text is perfect naturally on chrome and firefox without touching font-smoothing or anything else.
But on Mac / Safari 7 the text appears well then turns immediately thinner (too much thinner / not nice to read).

After doing some research [cf http://www.usabilitypost.com/2012/11/05/stop-fixing-font-smoothing/]
and some tests playing with

-webkit-font-smoothing    

It looks like Safari display the text first with :

-webkit-font-smoothing: subpixel-antialiased;

Then just after you got the flickering effect, when it is turning font to :

-webkit-font-smoothing: antialiased;

So it seems to me that I had no choice but to force

-webkit-font-smoothing: subpixel-antialiased;

to make my website consistent on all browsers.
I am using font-face Avenir Std Roman.

Some explanations to that Safari problem ? Any better solutions ? Could my font be part of the problem ?

Thanks.







HTML dropdown menu font change in Safari

Try using -webkit-font-smoothing: subpixel-antialiased;. This is a webkit specific property and it doesn't exist for non-webkit browsers. You can read more about this property here http://maxvoltar.com/sandbox/fontsmoothing/.

Google Web fonts not correctly rendering in Safari

Google Fonts provides three methods of import: < link >, @import or JavaScript). Regardless your choice, the request's response is always the same, a list of font faces.

The "url" descriptor of each font-face provides the paths where the binary should be picked. First, it will try the installed fonts in the OS, if fails, fetch in Google Fonts.

Somehow Safari don't get the right font for the desired "font-weight" if the font is in the OS. In my case, I set "font-weight" to 100, so it should use "Roboto-Thin", but it gets "Roboto-Light" instead.

The easiest solution is uninstall the font and let Google provide it (I did this to Roboto). If that is not good for you, there is another option: do not use the import methods described above and define the font faces yourself.

For these, paste the URL that Google provided in the browser, copy the CSS code provided and paste in your own CSS file.

e.g.:

# Firefox.
@font-face {
  font-family: 'Roboto';
  font-style: normal;
  font-weight: 100;
  src: local('Roboto Thin'),
       local('Roboto-Thin'), url(https://fonts.gstatic.com/s/roboto/v15/2tsd397wLxj96qwHyNIkxHYhjbSpvc47ee6xR_80Hnw.woff2) format('woff2'),

}
