So where are you expecting this information to come from?
The page has text in the
<h1>, that would do for the title.
fall autumn brown leaves save the date card
There is not much in the way of text for a description, the best I can see is:-
stylish, chic, fall wedding design
There is an image so you have that covered.
But how is this content put onto the page? I presume some type of database.
The same process that pulls this info to fill the page content could be used to populate the meta tags.
