I have created a SharePoint Page using Wiki page option. - I used the two column option and created the page. Added the html code for accordions using the Js and some css style I did that by using Insert-> Embedded code -> added the code in the box and it was added as a webpart and it solved my purpose. - But here is a new problem, I don't want the CSS to be applied to the other column of the page. How to avoid that.
Also, I want to change the color of the alternate header to grey, any code for that would really help, thank you. please help
