Comparison of browser engines (typography support)
This article compares web typography support for several browser engines.
Explanation of the tables[edit]
Engine | Status | Embedded in |
---|---|---|
WebKit | Active | Safari browser, plus all browsers hosted on the iOS App Store |
Blink | Active | Google Chrome and all other Chromium-based browsers like Opera and Microsoft Edge |
Gecko | Active | Firefox browser and Thunderbird email client, plus forks like SeaMonkey and Waterfox |
KHTML | Discontinued | Konqueror browser |
Presto | Discontinued | formerly in the Opera browser |
EdgeHTML | Discontinued | formerly in the Microsoft Edge browser |
Trident | Discontinued | Internet Explorer browser and Microsoft Outlook email client |
Values[edit]
These indicate the level of support for the given item in each engine. By default, the most recent version of the engine is implied. However, a specific version number can be listed; when this indicates full support, it's the initial version of the engine fully supporting the item.
Value | Meaning |
---|---|
Yes | Fully supported |
No | Has never been supported |
Partial | Only some values are supported |
Incorrect | Not implemented correctly in all cases |
Experimental | May be incomplete or buggy |
Nightly build | Currently in development; full support is expected |
Depends | Only supported for the specified conditions |
Dropped | No longer supported |
Support for CSS font resources[edit]
This section needs to be updated.September 2015) ( |
CSS3 specified a mechanism for downloading and displaying fonts within a web page.[spec 1] This table compare support for that mechanism. Note that Embedded OpenType (EOT) font download does not bring in the entire OpenType font and therefore, the most prominent feature of Open Type, ligature support, does not come with EOT. MSHTML before version 5.0 supports only EOT. EOT is not sufficient for smartfonts that rely on ligatures.
