Hiding Header and Footer on Landing Page only... Craft Theme

I’ve tried other solutions in here for code to hide the header and footer on my landing page, but none of them are working for me. Any help is greatly appreciated!

So far I’ve tried:

{% if page.url == ‘/pages/lmsl-and-aegenda’ %}

div#shopify-section-foote, header#SiteHeader { display: none !important;; }

{% endif %}

and

{% if page.url == ‘/pages/landing-page’ %}

div#shopify-section-foote, header#SiteHeader { display: none !important;; }

{% endif %}

and a few others…

@Cthom1964 , try this one

{% if page.url == '/pages/lmsl-and-aegenda' %}
   
{% endif %}

And

{% if page.url == '/pages/landing-page' %}
 
{% endif %}

That worked! Thank you!
