The following tables compare graphics compatibility and support for a number of layout engines within web browsers. Please see the individual products' articles for further information. This article is not all-inclusive or necessarily up-to-date.
Unless otherwise specified in footnotes, comparisons are based on the stable versions without any add-ons, extensions or external programs. Version numbers, if possible, are provided for features that are fully supported. Proprietary extensions are not included.

Used by the LG Smart TV platform to enable web content on TVs.

Values indicate the level of support in the most recent version of the layout engine, or (if a version number is given) in the specified version. Version numbers without any other value indicate the version at which the layout engine first fully supported the feature.
||Indicates that the layout engine fully supports this property/element when valid values are used.
||Indicates that the property/element is completely ignored.
||Indicates that the property/element is understood, but that not all values are supported. Supported values are implemented correctly.
||Indicates that the property/element is understood, but that it is not implemented correctly in all cases.
||Indicates that the property/element is understood, but supported under an alternate name. May be incomplete or buggy.
||Indicates that the property/element is no longer supported.
||Indicates that the property/element is supported to some extent in an experimental/nightly build. Future support is expected.
||Indicates that the property/element is supported only on certain platforms, or if certain settings are configured.
