I recently discovered the CSS Stylesheet. I've stylized all of my items to ease the process of importing word documents. The last item I'm trying to do is toggle the border button by default when you click an image.
the class is .aui-button image-border-toggle active last first

I know I can set the border using .confluence-embedded-image but then I cant get rid of a single border if I need to
I've already been able to set the default width with
.image-size-input {
width: 628px;
}
