Property 'float' does not exist on type 'CSSStyleDeclaration'

[sgnix]

Property float should be part of the CSSStyleDeclaration.

var left = document.createElement('div');
left.style.float = "left";

Returns error: Property 'float' does not exist on type 'CSSStyleDeclaration'

To access the CSS float property you have to use cssFloat.

Thanks @rielz, you seem to be correct.

Note: If you're referring to this property from JavaScript as a member of the element.style object, you must spell it as cssFloat. Also note that Internet Explorer versions 8 and older spelled this styleFloat. This is an exception to the rule that the name of the DOM member is the camel-case name of the dash-separated CSS name (and is due to the fact that "float" is a reserved word in JavaScript, as with the need to escape "class" as "className" and escape <label>'s "for" as "htmlFor").

This should potentially be revisited.

Note: If you're referring to this property from JavaScript as a member of the element.style object, in Firefox 34 and older you had to spell it as cssFloat. Also note that Internet Explorer versions 8 and older spelled this styleFloat. This is an exception to the rule, that the name of the DOM member is the camel-case name of the dash-separated CSS name (due to the fact that "float" is a reserved word in JavaScript, as seen in the need to escape "class" as "className" and escape 's "for" as "htmlFor").
