Customize the Kendo UI appearance using JavaScript

Currently, I am trying to modify the background color of certain controls using JavaScript. While I have figured out how to do this for DropDownList and ComboBox components, I'm facing difficulty with the DatePicker. The frustrating part is that there doesn't seem to be a universal method for accessing the necessary elements within each control. For instance, when changing the background color of a dropdownlist, I can access the "span" element like so:

$("#myDropDown").data("kendoDropDownList").span.css("background-color", "#BDD1FF");

On the other hand, for a combobox, I target the "input" element:

$("#myComboBox").data("kendoComboBox").input.css("background-color", "#BDD1FF");

Unfortunately, none of these methods seem to work for the kendoDatePicker. Is there a solution out there that someone might know? I've attempted direct CSS manipulation (similar to JQuery) but haven't had any success.

UPDATE: My requirement is to alter only specific controls within my forms, rather than all of them. This is why directly overriding the kendo CSS isn't feasible for me. Additionally, I need to apply this background change only when my view model is in edit mode. Therefore, being able to toggle classes dynamically is essential, which is why I'm considering utilizing JavaScript.

If you want to easily apply a specific color to your elements using CSS, you can define your own style like this:

.k-input {
    background: #BDD1FF !important;
}

Once you have set this up, you can use it on various elements without any hassle. For example:

$("#myKendoDropDown").kendoDropDownList().data("kendoDropDownList");
$("#myComboBox").kendoComboBox({}).data("kendoComboBox");
$("#myDate").kendoDatePicker({});

Keep in mind a couple of things:

Avoid using just background-color as KendoUI may have other background attributes that need to be overridden.
Using !important is necessary if you want to ensure your styling takes precedence over later definitions for background.

You can see an example of this method here: http://jsfiddle.net/OnaBai/Nxv3B/

EDIT: If you prefer to programmatically control which elements receive the styling, you can do so like this:

var dd1 = $("#myKendoDropDown1").kendoDropDownList().data("kendoDropDownList");

Create the widget first and then apply the custom styling like this:

dd1.wrapper.find(".k-input").css("background", "#BDD1FF");

Instead of following the method outlined above, consider not focusing on it being a Kendo DropDownList. The main issue arises when the widget is not fully loaded during Document.Ready most of the time. In such cases, simply treat it like any other normal element on the page until it finishes loading. This approach can save you significant amounts of time.

$("#myKendoDropDown1").css("width", 220);

It's important to note that while this solution may not be effective for adjusting background-color, it works well for making changes with other CSS properties.
