Create CSS for a panel container

Create the CSS to make a web panel according to the specifications. Example CSS for most of it is already available. This should be an easy job. ## Deliverables I need the CSS to create a web page panel as shown in the picture. The CSS should be based on the Wijmo CSS theme "Artisto", which can be found here: [login to view URL] I want a panel, that has the same look as the Wijmo Expander widget, found here: [login to view URL]|overview Specifically, from the wijmo example, I want the header colors, outline, and text in the header. See the attached picture for an example of what the final project should look like. All of the required CSS needs to be copied into a file and given its own class name, called "panel". It is fine to copy the CSS from the given examples above, but I want my own CSS file that has all of the needed CSS values, but *only* the needed values for my panel. I need to be able to edit the CSS values, so that any and all of the attributes can be updated. For example, I want to be able to change the size of my panel by only changing two values, width and height.
