The style prop on regular DOM elements should be in the form of an object where the keys are the css attributes.
Example:
<div style={{ width: "100%", backgroundColor: "black" }} />
Notice that in the case of attributes containing dashes, they become camel cased. For instance background-color becomes backgroundColor.

Typescript Type support for style objects
I'm working with React Typescript and Emotion. So far I have used template strings, but I'd like to gradually move to style objects. I'd like to be able to declare a style object, get type support from the editor, and then pass it to a css function, or a styled component. More on github.com

element.style.color = "red"; IS javascript. AFAIK typescript doesn't change anything about the dom API, it only adds things like static typing and enums.
Actually, I don't think this question is related to typescript at all.

Is any[] the TypeScript equivalent of !important in CSS?
Yep. In almost all cases there is a better type than any. Even when you don't care about the type or don't know it (like a pass-through function or some API types you don't care about), you can use unknown or some generic type. any just renders TS basically useless past that point.

Here, we avoid using type assertions and strive for type safety by typing as narrowly as possible. To make the TypeScript compiler recognize CSS variables, we can explicitly spell them out, like the following:

r/typescript on Reddit: CSS Styling in Typescript
October 22, 2019 -
I'm fairly new to Typescript and I need to know how to style elements with Typescript. I already know that:
element.style.color = "red";
in Javascript is equivalent to
element.setAttribute("style", "color: red")in Typescript, but I'm having a few problems with converting a couple of other things, such as:
element.style.removeProperty("color");or
if (element.style.borderColor == "red")
Any help would be much appreciated. The lack of documentation and answers I can find using Google on these problems I encounter is disappointing to say the least.

Typescript gets transpiled into vanilla js so that browsers can understand it. Typescript syntax is mostly the same.

Try using setAttribute. TypeScript does not have the style property on Element.
Copyelement.setAttribute("style", "color:red; border: 1px solid blue;");

The API you were searching for is: https://developer.mozilla.org/en-US/docs/Web/API/CSSStyleDeclaration/setProperty
Copypublic static setStyleAttribute(element: HTMLElement, attrs: { [key: string]: string }): void {
for(const [key, value] of Object.entries(attrs)) {
element.style.setProperty(key, value);
}
}
And hyphen is not allowed in object keys, so use ' here, too:
Copylet elem: HTMLElement = document.getElementById('myDiv');
setStyleAttribute(elem, {'font-size':'12px', color: 'red', 'margin-top': '5px'});
