Fullwidth button and SEO landing page

Hello!

Newbie question, from a SEO perspective, my landing page is all pictures and buttons with text. IPSCBUTIKEN

From a SEO perspective the landning page is lacking h1 and h2 OR does the text in the buttons do it for the crawlers?

CSS inline the button text to h2 made some undesired layout issues with button icon, and split the button in two full width parts.

<h2 style=”color:#ffffff; font-size: 24px; “>Vapen</h2> button text for example

Also I added a structured “screen options hidden-not show” h1 h2 text, high on my landing page, will that do anything for the crawlers? =)

“<h1>IPSCBUTIKEN – ARE YOU READY</h1>
<h2>Rödpunkt pistol</h2>
<h2>Rödpunkt gevär</h2>
<h2>Vapen</h2>
<h2>Begagnade vapen</h2>
<h2>Montage rödpunktsikte</h2>
<h2>Montage rödpunktsikte gevär</h2>
<h2>Toni System</h2>
<h2>Guga Ribas</h2>
<h2>DKYX – Hölster och magasinshållare</h2>
<h2>Skytteglasögon</h2>”

What would best practice be for a picture/button landing page?
