Remove header

I need some help removing the header when inside the articles?

I tried this, but then i the header disappears all the time:

`<style>
body:not(.page-template-page_front-page) .site-branding {
display: none;
}
</style>

Hi,

Please try these css code instead:

body:not(.home) .branding-wrapper {
    display: none;
}

Thank you !!
