How could I join a smaller and a bigger div with rounded edges?

Tags: css,html

Problem :

I currently have two divs on my site:


Notice that both have border [same color as the div] and they also have border radius.

I want to achieve this:

enter image description here

So I want them to join. How can I make this happen? If I can do it, is pure CSS and HTML enough or do I need jQuery and JS as well?

I though of making one large div of the two and then just setting a background that is similar to the two being united, but this is a not perfect for me because I have another object immediately below div 2.

So how can I do it?

Thanks in advance.

Solution :

Set the divs next to each other and remove the border-radius from the big div's top right corner and from the left side of the smaller one.

#big {

#small {
