Question

I want to use css3 & google web fonts for the navigation (instead of graphics, for performance reasons).

Does anyone have experience with this? Are there drawbacks/limitations to using Google Web Fonts for a mobile client? Thank you.

Answer 1

What about performance? Will web fonts slow down my page?

If a page
uses web fonts, then the font files have to be downloaded to the site
visitor’s computer before they can be displayed initially. The font
files are served compressed for a faster download. After that initial
download, they will be cached in the browser. As the Google Web Fonts
API becomes widely used, your visitors will be likely to already have
the font you’re using in their browser cache when they visit your
page.

In general, however, you should keep an eye on the size of the font
files you are serving. Also be aware that using web fonts may result
in the browser making more HTTP requests than would otherwise be
necessary.

Compared to using images to display a lot of text on a page, web fonts
are likely to enhance the performance (and maintainability, and
accessibility) of your page. In other situations, however, they might
add to the overall weight of your page.
