I created a homepage (HTML) in Pages, however some of the CSS doesn't look the same as when I'm in the forum. For example the pop-up menu when you click your username is much larger. 

Is there something to do so that the homepage has the same style as the other pages? 
 

Are you just using existing blocks?  If so, what blocks?   Do you have a URL that you can link to that would show what you're seeing?

It's an HTML page (not a builder page). I've added a Topic Feed block at the bottom.

The issue is with the pop-up menu at the top right when you click your username, that looks bigger than on other pages. Maybe I'm using a CSS file that conflicts with IPS CSS? 

 

We are unable to assist with custom coding unfortunately. I will move this to our commmunity support area, as there will be people who may be able to assist you with this.

I was finally able to resolve this. Some of the custom CSS I had added to that page was conflicting with some of the Invision Community CSS.
