My brain is going crazy on figuring out how to modify the `background color` within a `div` that has a `class`, with an inline style controlling the color of the div. 

I'd like to know how I would be able to change the background color from within one div but leave the other div's background color intact. As you can see, the div's contain the same class names, but the inline style color is what I'm trying to update. I'm also unable to modify the structure of the html page, otherwise, this would be a piece of cake. 

With a css class I can write something like this to look at the current `class` and replace it with another `class` but In this situation this isn't an option since this syntax would change all the divs with the similar divs.

```
$('.tx-cal-event').toggleClass({"sx-abc-event"});

<div class="nx-cal-event nx-cal-event-month" style="background-color: rgb(182, 232, 198);"></div>
<div class="nx-cal-event nx-cal-event-month" style="background-color: rgb(128, 128, 128);"></div>
<div class="nx-cal-event nx-cal-event-month" style="background-color: rgb(166, 166, 166);"></div>

```

I imagine to somehow identify the one color in a div and make it transparent via a button. I have the button variable but its the actual syntax for changing the color when it is referenced in an inline style element. 

Any help would be appreciated.
