Relative links to pages in custom code?

Can you easily link to an already created page inside a custom html snippet? My site is not published yet. 

So far I'm doing this, which I know will not work until I publish my site, but can I do something like <a href=".../about-us"> ?

<a href="https://mysite.com/services/creative-engagement" class="service-card service1">
    <h3>
      Creative<br /> Engagement
    </h3>
 </a>
