Font style matcher

If you're using a web font, you're bound to see a flash of unstyled text (or FOUC), between the initial render of your websafe font and the webfont that you've chosen. This usually results in a jarring shift in layout, due to sizing discrepancies between the two fonts. To minimize this discrepancy, you can try to match the fallback font and the intended webfont’s x-heights and widths. This tool helps you do exactly that.

if ('serviceWorker' in navigator) { navigator.serviceWorker.register('/public/vendors/font-style-matcher/sw.js', {scope: '/font-style-matcher/'}).then(_ => { console.log('service worker is cool 🐳'); }).catch(e => { console.error('service worker is not so cool 🔥', e); throw e; }); } Fallback font Font size: 16px

Google Chrome (ERR_EMPTY_RESPONSE)

WHM/cPanel AutoSSL issue with Google Chrome (ERR_EMPTY_RESPONSE)

Today few clients complained about their websites not working in Google Chrome.

The reason that this problem affects Chrome browsers is because it uses the POLY1305 cryptographic algorithm and this triggers the problem in OpenSSL on the server.
