use new accordion class

Hi,
in Eximium template there is this class:
.yjsgaccGroup {
display: block;
position: relative;
padding: 0;
margin: 0 0 3px 0;
border: 1px solid #ddd;
-webkit-border-radius: 3px;
-khtml-border-radius: 3px;
-moz-border-radius: 3px;
border-radius: 3px;
}

If in the custom.css file i create another class, for example
.yjsgaccGroup2 {
display: block;
position: relative;
padding: 0;
margin: 0 0 3px 0;
/* border: 1px solid #ddd; */
-webkit-border-radius: 3px;
-khtml-border-radius: 3px;
-moz-border-radius: 3px;
border-radius: 0px;
}
when i insert an accordion in my article I cannot use the second class.
Instead, if I inspect the page with mozilla and I rename the class (like shown in the attacched image), I obtain what i want.
My goal is to have some accordion with standard Eximium class and some other accordion with my new class.
How can I do this?
Thanks.

Hello michy80.
When you create your accordions you can add your custom ID to it.

After that you can use your id class and add it to the custom.css file, like this:

#myid .yjsgaccGroup{
your css
}

Hi Arefund,
and thanks for your answer. I tried to do what you wrote but it does not work (maybe i did some errors??).
In attachment what I did following your advices.
Waiting for your answer.
Thanks again

Hi Arefund,
have you got some news about y request?
Many thanks

Can you please post your site link so I can check it live, might be that some other class is taking over the style.

Hi,
this is the page where i tried to do what you wrote to me.
The last accordion "My title" is where i need to insert another accordion class
PS: i've not bought the licence removal because the site is not completed yet.

Let me know, thanks

As you can see here http://prntscr.com/e2qdpv i checked the class and its working properly.
When you add your css attributes and they are not working try to add !important to it.

Hi Arefund,
thank you for your answer. Adding !important to the css rule it works!
Thank you again!
