Templates — Layout Reference

How Hugo templates work

Hugo uses the Go template language. All templates live in themes/maks/layouts/.

Key concepts:

{{ .Field }} — output a field value
{{ range .Items }}...{{ end }} — loop over a collection
{{ if .Condition }}...{{ end }} — conditional block
{{ partial "name.html" . }} — include a partial, passing current context
{{ block "name" . }}...{{ end }} — define a named block (in baseof)
{{ define "name" }}...{{ end }} — override a block (in child templates)
{{ "path" | relURL }} — convert path to relative URL
{{ .Value | funcName }} — pipe: pass value into a function

baseof.html — master template

Path: themes/maks/layouts/_default/baseof.html
Rendered for: every page on the site (acts as a wrapper)

This is the foundation of the entire site. Every other template extends baseof via define blocks.

Blocks that can be overridden

Block	Location in baseof	Purpose
`{{ block "head" . }}`	inside `<head>`	Additional `<link>` or `<meta>` tags
`{{ block "main" . }}`	main content area	Page content
`{{ block "scripts" . }}`	before `</body>`	Inline JS specific to the page

What always renders (cannot be overridden)

Desktop nav .desk-nav — logo + links + lang-toggle + theme-toggle
Mobile nav .mob-nav — logo + burger
Mobile drawer .mob-drawer — slide-out menu
Mobile bottom nav .mob-bottom-nav — bottom bar with icons
Footer — logo + stack + location + year
<script> — inline: toggleTheme(), setLang(), toggleMobMenu(), closeMobMenu(), restore from localStorage

Note: site.js is not loaded from baseof! Functions are inlined directly in baseof to guarantee execution order. site.js in static/js/ is a legacy file — its functions are duplicated inline.

How theme switching works

<html data-theme="dark">   ← attribute on <html>

CSS reads the attribute via [data-theme="light"] and switches variables. The value is stored in localStorage.theme.

index.html — home page

Path: themes/maks/layouts/index.html
Rendered for: /
Defines block: main

Home page sections

CSS class	Content	Data source
`.hero`	Heading + description + buttons	Hardcoded in template
`.panel .recent-posts`	Last 5 posts	`{{ range first 5 .Site.RegularPages }}`
`.panel .kb-section`	KB quick links	Hardcoded links
`.panel .certs-section`	Cert widget	`{{ partial "certs-widget.html" . }}`
`.cert-grid`	cert cards	`{{ partial "certs-widget.html" . }}` — counts computed dynamically

_default/single.html — article page

Path: themes/maks/layouts/_default/single.html
Rendered for: any single page without a specific template
Used by: all articles /posts/*/, /kb/*/, /kb/docs/*/ (when no own template exists)
Defines blocks: head (JSON-LD for EN pages), main, scripts

`main` structure

.page.prose-page
  breadcrumb.html      ← partial: maks.top / {section} / {title}
  article
    .post-header
      h1               ← .Title
      .post-meta
        .post-date     ← .Date.Format "02/01/2006"  (dd/mm/yyyy)
        .post-meta-tags
          .tag × N     ← range .Params.tags → links to /tags/{tag}/
    .prose             ← {{ .Content }} (markdown body → HTML)
    .back-link         ← ← Back to {section}
  .toc-aside           ← empty div, populated by JS

`head` block — JSON-LD structured data

Injects <script type="application/ld+json"> with Schema.org Article for all EN pages (page_lang: "en"). Fields: headline, description, url, datePublished, dateModified, author, publisher.

`scripts` block

Loads static/js/article.js (reading bar, ToC, copy buttons, lightbox). If code_toggle: true in frontmatter, sets document.body.dataset.codeToggle = 'true' before the script loads.

_default/list.html — page listing

Path: themes/maks/layouts/_default/list.html
Rendered for: any section without a specific template (/kb/docs/, /certs/ if no own template)
Defines block: main

.page
  .sec-title           ← .Title | default .Section
  .posts-list
    .post-card × N     ← range .Paginator.Pages
      .post-card-meta  ← date + first 2 tags
      .post-card-title ← .Title
      .post-card-desc  ← .Description or .Summary (truncated to 120 chars)
  pagination.html      ← {{ partial "pagination.html" . }}

posts/list.html — blog listing

Path: themes/maks/layouts/posts/list.html
Rendered for: /posts/
Overrides: _default/list.html
Adds: Pagefind search

Difference from _default/list.html: explicit page_lang ne ru filter, adds .tags-header via search-box.html partial, loads pagefind-search.js.

How Pagefind works:

GitHub Actions runs pagefind --site public after hugo build
Pagefind crawls public/ and creates an index in public/pagefind/
On the client, pagefind.js loads lazily (only on first search input)
Results appear in an absolutely positioned div below the input

posts/linux-namespaces.html — interactive page

Path: themes/maks/layouts/posts/linux-namespaces.html
Rendered for: /posts/linux-namespaces/
Loads: styles/ns.css via head block, js/ns.js via scripts block

Fully custom layout with a two-column structure:

Left column: markdown content + namespace map + grid + cheatsheet
Right column: ToC + progress bar

Namespace data (nsData, cheatData) is defined in ns.js.

about/single.html

Path: themes/maks/layouts/about/single.html
Rendered for: /about/

Renders a profile card .about-strip with data from hugo.toml [params]:

HTML	Source
`.about-name`	`.Site.Params.author`
GitHub / LinkedIn / Telegram links	`.Site.Params.github` / `.Site.Params.linkedin` / `.Site.Params.telegram`
`.prose`	`.Content` (body of `about.md`)

Then inserts {{ partial "certs-widget.html" . }} — the same cards as on the home page.

certs/single.html — cert overview page

Path: themes/maks/layouts/certs/single.html
Rendered for: /certs/lpic-2/, /certs/lpic-1/, etc.
Loads: styles/cert.css via head block

Accordion build algorithm

1. $allPosts = all pages in the "posts" section
2. $prefix   = .Params.post_prefix (e.g. "lpic2")
3. For each exam in .Params.exams:
   For each topic in exam.topics:
     $topicPattern = "{prefix}-{topic.num}-"
     $topicPosts   = filter: pages whose BaseFileName starts with $topicPattern
     → if $topicPosts is not empty → render accordion with links

Function toggleTopic(btn): toggles .open class on .cert-topic, animates max-height on .cert-topic-body.

kb/section.html — KB index and sub-sections

Path: themes/maks/layouts/kb/section.html
Rendered for: /kb/ (root index) and /kb/{sub-section}/ (sub-section landing pages)
Note: kb/single.html and kb/list.html were deleted — KB articles fall through to _default/single.html.

Uses {{ if .Sections }} to branch between two layouts:

Root /kb/ (has child sections):

.page
  breadcrumb.html
  h1 "Knowledge Base"
  .kb-section-title "Site Documentation"
  .kb-cards  ← docs pages
  .kb-section-title {group}  ← for each group: "Linux Core", "Networking", etc.
  .kb-cards
    .kb-card.kb-card-section × N  ← sub-sections (from .Sections)
    .kb-card × N                  ← regular kb pages with Params.group

Sub-section /kb/{name}/ (no child sections):

.page
  breadcrumb.html
  h1 ← .Title
  p.sec-desc ← .Description
  .kb-cards
    .kb-card × N  ← .Pages.ByTitle

taxonomy/tag.html — tags page

Path: themes/maks/layouts/taxonomy/tag.html
Rendered for: /tags/

Embeds POSTS[] array and currentTag inline (Hugo-generated, EN only), then loads static/js/taxonomy.js which handles all filter/render logic. Clicking a tag button filters the array and re-renders .posts-list via innerHTML.

partials/

certs-widget.html

Included on the home page (index.html) and about (about/single.html). Article counts and progress % are computed dynamically from post_category + expected_articles / progress_pct in each cert’s frontmatter. See Frontmatter for cert fields.

search-box.html

Renders the search input UI. Accepts .placeholder param. Used in index.html, posts/list.html, taxonomy/tag.html.

pagination.html

Accepts a context with .Paginator. Always shows first/last page, cur-1, cur, cur+1, inserts ··· for gaps.

shortcodes/

`code`

{{< code lang="bash" label="example" >}}
command
{{< /code >}}

Parameter	Type	Default	Description
`lang`	string	`"bash"`	Language shown in block header
`label`	string	—	Additional label (small text)

Renders .code-block with a copy button. .Inner — body between tags, passed through htmlEscape.

`ns-card`

{{< ns-card name="PID" flag="CLONE_NEWPID" icon="⚙️" color="#7c3aed"
    summary="Process ID isolation"
    desc="Detailed description..."
    host="PID 84521 on host"
    ns_view="PID 1 inside"
>}}
{{< /ns-card >}}

Parameter	Required	Description
`name`	yes	Namespace name (PID, NET, UTS…)
`flag`	yes	Kernel flag (CLONE_NEWPID)
`icon`	yes	Emoji icon
`color`	yes	CSS color (hex), used for `--card-color`
`summary`	yes	Short description in the header
`desc`	yes	Full description in the expanded body
`host`	no	Value on the host side (visual block)
`ns_view`	no	Value inside the namespace (visual block)

.Inner — arbitrary markdown inside the tags (e.g. code block).
