To create a library of autonomous blocks for generating dynamic websites. The CMS will automatically assemble pages by randomly selecting different blocks (header, body, footer, etc.).

The blocks should be independent and easily combinable with each other in any order.

Payment

For the project or an hourly rate.

Composition of Blocks

Header – 5 options
H1-blocks – 6 options
Body-blocks – 11 options
Footer – 12 options

See the list and examples of blocks in the file:
Google Sheets – block layouts

General Requirements

Single CSS file for all blocks
All styles should be stored in one CSS file.
One class per element
Each HTML element is allowed only 1 class.
Autonomy of blocks
- Blocks should not depend on each other for styles.
- Each block has a unique prefix in class names.
- The layout should not break with any combination of blocks.
Margins between blocks
- Provide vertical margins (margin/padding) so that blocks look good in any combinations.
- It is preferable to use padding inside blocks so that content does not stick to the edges.

Variable system for colors
All colors and backgrounds should be assigned through CSS custom properties (variables).

Variables are connected through :root { ... } using constants:

:root {
  --header-bg: var(--{{ synonyms.header }});
  --header-btn-login-bg: var(--{{ synonyms['header__buttons-login'] }});
  --header-btn-login-text: var(--{{ synonyms['header__buttons-login'] }}_text);
  --header-btn-signup-bg: var(--{{ synonyms['header__buttons-signup'] }});
  --header-btn-signup-text: var(--{{ synonyms['header__buttons-signup'] }}_text);

  --body-bg: var(--{{ synonyms['wrapper'] }});
  --body-text: var(--{{ synonyms['header__text'] }});
  --body-btn-bg: var(--{{ synonyms['slot__button'] }});
  --body-btn-text: var(--{{ synonyms['slot__text'] }});
  --h1-bg-top: var(--{{ synonyms['block-h1__top'] }});
  --h1-bg-main: var(--{{ synonyms['block-h1__h1'] }});
  --slot-bg: var(--{{ synonyms['block-slot-with-group-row__slots-wrap-local'] }});

  --footer-bg: var(--{{ synonyms['footer'] }});
  --footer-color: var(--{{ synonyms['footer__color'] }});
}

Inside blocks, use only variables, not hard-coded colors.

Layout Standards

HTML5, semantic markup
Mobile-first, responsiveness (flex/grid)
Minimum dependencies (no external libraries).
Images – via <img> or <picture>, icons – via SVG.
Fonts and sizes – relative (rem, %).
All blocks should look correct at widths 320px – 1920px.

Technical Details of Blocks

Header (5 options)

Composition: logo, menu, buttons (Login/Signup), possibly a search bar.
Background – via --header-bg.
Buttons – via --header-btn-login-bg, --header-btn-signup-bg.

H1-blocks (6 options)

Composition: H1 title, subtitle/description, background/gradient.
Use --h1-bg-top, --h1-bg-main for styling.

Body-blocks (11 options)

Composition: cards, text sections, galleries, CTA blocks, blocks with buttons.
Background – --body-bg, text – --body-text.
Buttons – --body-btn-bg, --body-btn-text.

Footer (12 options)

Composition: navigation, copyright, social media, quick links.
Background – --footer-bg, text – --footer-color.

Quality Assurance

Each block is tested separately (standalone).
Testing combinations of blocks (random order) – to ensure there are no "sticking" or visual bugs.
Responsive test (smartphone, tablet, desktop). Priority is given to mobile.

Hello! I have extensive experience in developing modular and scalable front-end systems, and your project to create a library of autonomous blocks for dynamic websites perfectly matches my requirements. I specialize in creating responsive semantic layouts using HTML5 and CSS3, where each component is completely independent, reusable, and styled with a centralized variable system, ensuring consistency and flexibility. Following your requirements, I will implement the "one class per element" concept, unique prefixes, and custom CSS properties so that all blocks can be combined in any order without conflicts. I will also apply a mobile-first approach, conduct testing at breakpoints (320–1920 pixels), and ensure flawless responsiveness using Flexbox/Grid. All projects will be optimized for performance, accessibility, and cross-browser compatibility, taking into account your requirements for autonomy and ease of maintenance. With my experience in creating customizable CMS solutions, I can build a reliable block library that meets your technical and design expectations.
