<h1>Inter variable font test</h1>
|
|
<p>
|
|
Tests how the Inter variable font is rendered by the web browser
|
|
with the traditional style properties <tt>font-weight</tt> and
|
|
<tt>font-style</tt>.
|
|
</p>
|
|
<p>
|
|
We can always use <tt>font-variation-settings</tt> to gain full control
|
|
over variable font axes, which works as expected in all major browsers.
|
|
This document does <em>not</em> make use of <tt>font-variation-settings</tt>.

<h2>Known issues with variable fonts:</h2>
|
|
<ul>
|
|
<li>
|
|
<b>Most browsers as of August 2019:</b>
|
|
<ul>
|
|
<li>
|
|
Mapping of negative slant axis to <tt>font-style:italic</tt> has no effect.<br>
|
|
</li>
|
|
<li>
|
|
Mapping of negative slant axis to <tt>font-style:oblique</tt> has no effect.
|
|
</li>
|
|
<li>
|
|
All current stable versions of major web browser supports
|
|
<tt>format("woff2-variations")</tt>
|
|
for font url format in <tt>@font-face</tt> declarations.
|
|
</ul>
|
|
</li>
|
|
<li>
|
|
<b>Safari:</b>
|
|
<ul>
|
|
<li>
|
|
Defining <tt>font-weight</tt> in <tt>@font-face</tt> causes
|
|
slnt axis to be maxed out by default, causing <tt>font-style:normal</tt>
|
|
to be fully slanted/oblique/italic. This is counter-acted by using a
|
|
specific <tt>@font-face</tt> for Safari that doesn't define
|
|
<tt>font-weight.</tt>
|
|
(Last confirmed version: Safari 12.1)
|
|
</li>
|
|
<li>
|
|
<tt>font-synthesis:none</tt> is required or else
|
|
<tt>font-style:italic</tt> causes "double-slant" —
|
|
the slnt axis gets maxed out as expected, but then faux oblique is
|
|
applied on top of it, causing an overly extreme slant.
|
|
This means that <tt>font-style:italic</tt> can't be used in Safari,
|
|
and instead we use <tt>font-style:oblique</tt> which works in all
|
|
major browsers. Note that this effects <tt><em></tt> and
|
|
<tt><i></tt> which in Safari implicitly has
|
|
<tt>font-style:italic</tt>.
|
|
(Last confirmed version: Safari 12.1)
|
|
</li>
|
|
</ul>
|
|
</li>
|
|
<li>
|
|
<b>Chrome:</b>
|
|
<ul>
|
|
<li>
|
|
Rendering of overlapping shapes causes "blobs" or "ink bleed".
|
|
Overlapping shapes, like the angle + horizontal stem of "A" are
|
|
rendered in separate MSAA passes and later combined as bitmaps,
|
|
causing a multiplication effect on the alpha channel.
|
|
</li>
|
|
<li>
|
|
Passing explicit degrees to oblique (e.g. <tt>font-style:oblique -5deg</tt>)
|
|
is not supported. (Last confirmed version: Chrome 75)
|
|
</li>
|
|
<li>
|
|
For fonts with negative <tt>slnt</tt> values, as per the OT spec,
|
|
<tt>font-style:oblique</tt> has no effect (not mapped to negative max of slnt axis.)
|
|
(Last confirmed version: Chrome 75)
|
|
</li>
|
|
<li>
|
|
Mapping of negative-value <tt>ital</tt> and <tt>slnt</tt> axis
|
|
to <tt>font-style:italic</tt> is not supported.
|
|
</li>
|
|
<li>
|
|
<b>Version <75:</b> Mapping of positive-value <tt>ital</tt> and <tt>slnt</tt> axis
|
|
to <tt>font-style:italic</tt> is not supported.
|
|
</li>
|
|
<li>
|
|
<b>Windows only:</b> kerning is incorrect and
|
|
there are issues with ClearType where for example a lower-case "r"
|
|
(without hints) might be rendered much lower than a lower-case "n".
|
|
(Last confirmed version: Chrome 69)
|
|
</li>
|
|
</ul>
|
|
</li>
|
|
<li>
|
|
<b>Firefox:</b>
|
|
<ul>
|
|
<li>
|
|
For fonts with negative <tt>slnt</tt> values, as per the OT spec,
|
|
<tt>font-style:oblique</tt> has no effect (not mapped to negative max of slnt axis.)
|
|
(Last confirmed version: Firefox 68)
|
|
</li>
|
|
<li>
|
|
<b>Version <68:</b> Mapping of <tt>ital</tt> axis to <tt>font-style:italic</tt>
|
|
is not supported.

</li>

</ul>

<b>Edge:</b>
|
|
<ul>
|
|
<li>
|
|
Mapping of <tt>ital</tt> axis to <tt>font-style:italic</tt>
|
|
is not supported, nor is Mapping of <tt>slnt</tt> axis to <tt>font-style:oblique</tt>.
|
|
Note: We use separate italic and roman font files for Edge in this
|
|
test, which is why intermediate oblique degrees are displayed as either
|
|
fully slanted or not slanted at all when viewing this in Edge.
|
|
(Last confirmed version: Edge 42)
