Hi
Thought it might be useful to share installation advice for fonts from Optimo.ch as it's taken a while to work this out. It's probably a basic process for anyone that knows what they're doing. For this, I'm using Plain Medium.
Step 1
Package of files from Optimo contains, CSS, SVG and EOT. These are be added to a (new) folder called 'fonts' within: public_html/wp-content/themes/lay/. You'll need to access your domain to add these.
Step 2
Add this to 'Lay Options > Custom CSS and HTML' in both Desktop and Mobile:
@font-face {
font-family: 'PlainMedium';
src: url('/fonts/PlainMedium-Regular.eot'); /* IE9 Compat Modes /
src: url('/fonts/PlainMedium-Regular.eot?#iefix') format('embedded-opentype'), / IE6-IE8 /
url('/fonts/PlainMedium-Regular.svg#svgPlainMedium-Regular') format('svg'); / Legacy iOS */
}
Step 3
Add a new webfont in 'Lay Options > Webfont'
Font name: (same as font-family above)
Link tag: <link href="/wp-content/themes/lay/fonts/PlainMedium-Regular.css" rel="stylesheet" type="text/css">
font-family: 'PlainMedium', sans-serif;
Step 4
Head into 'Text formats' and change the Font Family to the chosen font.
Step 5
New font should be installed across the site.
Hope I've covered everything and of use to someone else.
