        Sets value of an element by CSS selector.

        Parameters
        ----------
        selector: str
            A CSS selector to search for. This can be any valid CSS selector.

        value: str
            The value to set on the element matched by the selector.

        clear: bool
            Whether or not we should clear the element's value first.
            If false, value will be appended to the current value of the element.

        blur: bool
            Whether or not we should blur the element after setting the value.
            Defaults to True
