Hi,
Providing assistance is pretty tough if we can’t see what you’re working on. Any chance you can link us to atleast, a dev or staging site?
But to try to answer the question: You can definitely do this w/ custom CSS.
If you want all links on the page to have the same style you simply use something like this:
body a{
/* your style here */
}
If you want to style something specific like blog post list title link you can try this:
.entry-title a{
/* your style here */
}
Note: These are just examples. We can’t really determine which CSS selectors to be used for your site specifically as we’ve yet to inspect your site.
