Webflow blog Styling difference in preview mode compared to original published blog

I am accessing one of our client website in Webflow platform using the Guest Access role. I added 2 blogs and they are currently in drafts. On previewing the blogs I created I noticed the style is different from the blogs they have published on their website.

I double checked by previewing their already published blog in Webflow editor and there also the stylings look different compared to the actual blog.

How can I preview the draft blogs so that I can see the same look once it is published in their website?

can you provide a read-only link please.
