Nimmo 1.2.8 – One Page Theme

Nimmo is a classic creative one-page theme: you’re selling a studio, app, freelancer, small agency. One strong homepage with sections, anchor menu, a few case studies, a contact block, done. I reach for it when the site is basically a pitch deck and nobody wants to babysit a complicated blog or a multi-level catalog.

The flip side: the whole site experience depends on front-end JavaScript behaving nicely. If your cache/optimization stack is aggressive, Nimmo-style themes are the first to show cracks (smooth scroll, sticky header offsets, animations firing late).

What controls the layout (and where the “one-page” logic lives)

In practice, Nimmo setups usually boil down to:

• A Front Page template (often front-page.php / a dedicated “One Page” template). That’s the file that decides what sections render and in what order.
• Section content is typically stored either:
  • as normal page content (builder blocks/shortcodes inside the homepage), or
  • in theme options / custom fields (titles, buttons, background images), saved in wp_options / post meta.
• Navigation uses anchor links (#about, #work, #contact). The theme JS intercepts clicks and does smooth scrolling + active-state highlighting.

If you want to change “how it looks”, you mostly live in:

• Customizer / Theme Options (colors, typography, header behavior).
• The homepage editor (reordering sections, swapping images, editing text).
• CSS overrides in Customizer → Additional CSS (fastest safe tweaks).

If you want to change “how it behaves” (scroll offsets, when animations trigger, how the sticky header is calculated), that’s theme JS territory. I don’t edit parent theme files for that unless there’s no alternative—updates wipe it.

Where it usually breaks (real causes, fast fixes)

1) Anchor menu scrolls to the wrong position (header covers the section)
Root cause: sticky header height not accounted for (and WP admin bar on logged-in users makes it worse).

Fix:

• First check if the theme has a “Scroll offset / Sticky header height” option in its panel.
• If not, adjust via a tiny CSS target offset trick (safe, update-proof): add scroll-margin-top to section wrappers (works if sections have IDs).
  Example in Customizer → Additional CSS:

  section[id] { scroll-margin-top: 90px; }
  
• If it’s only broken when logged in, set offset to include the admin bar too.

2) Animations/counters/parallax don’t run (or run once, then freeze)
Root cause: JS execution order after optimization (defer/delay), or missing dependencies.

Fix I use:

• In your optimization plugin (WP Rocket / LiteSpeed / Autoptimize), don’t delay jquery-core.
• Exclude the theme’s main script from delay (find it in DevTools → Network; it’s usually the largest theme .js file).
• DevTools → Console: one uncaught error stops the entire animation chain. Fix the first error, not the last symptom.

3) Contact section shows, but the form doesn’t submit / spinner forever
Root cause: the form plugin isn’t active, or its AJAX script is delayed/cached weirdly.

Fix:

• Confirm the form plugin is installed and active (most one-page demos rely on a form plugin rather than a custom PHP form).
• If it’s AJAX-based, exclude its script from delay and check DevTools → Network for the POST request (is it 200, 400, 403?).
• If you see 403, it’s usually a security plugin/WAF rule, not the theme.

License / activation / updates (plain language)

The theme normally runs without a license key, but without activation you typically lose auto-updates, vendor support, and sometimes demo importer access.
In my package it’s activated and working — I tested it.

Manual update path:

• Appearance → Themes → Add New → Upload Theme (ZIP), or replace via SFTP.
• Any edits in the parent theme will be overwritten. For PHP/template changes, use a child theme. For styling, keep changes in Customizer/child CSS.
