Help with styling again - can not find file

Hello, can you help me with finding the file to edit to style another link? I can't find any place in the article.php override. I want to make this link look like the gray button link I have on the same page, but have no idea where to do this.

Please see my screenshot. Where it says, "Visit A Sunset Chateau online for their latest packages and specials," that red link is what I want to look the same as the light gray rectangular button with the chevron icon/pointer that says "See more..."
Thank you for your help with this!

Hi there,
1.) Live Url please
2.) Please use the dev modus of your Browser to inspect the links and css

We are committed to help you with any type of support query, however we can't provide extensive help in terms of customizations. In general customizations may look simple but you will require solid knowledge of web technologies and programming skills to do them or hire a professional who can do it for you.

Hi, I usually do the customizing using the web developer extension in my browser too, and then edit the css, but this calls for a php file to be edited, I'm sure because there is no place to add css styles that is easy to find. The article.php file is not it. Just need to know which php file to edit.

The url is password protected so can't give this publicly. Is there a way I can send you the password separately? Just one look and I'm sure you'll be able to tell me which file.

Hi again, thanks for info.
But the link can not have the same look as the module on the right side.
But you can add a class "btn" to look a lil bit similar

<a rel="nofollow" target="_blank" href="xxxx.com" class="btn">Visit A Sunset Chateau online for their latest packages and specials.</a>
