Structured JSON-LD Schema Creator
Generate schema.org markup for local services or businesses. Structured schema helps Google display rich search results (reviews, price metrics, maps).
The SEO Value of Schema Markup and JSON-LD
Structured schema markup is a collaborative vocabulary created by major search engines (Google, Microsoft, Yahoo, Yandex) to define entity definitions clearly. By implementing structured JSON-LD data into your HTML templates, you help Google's algorithm determine what your content represents, not just what it says.
When Google crawls a site containing local service schema, it can translate address, coordinate, price, and email entities directly into Google Maps search listings, local knowledge panels, and review snippets in search engine results pages (SERPs). This structured integration significantly increases search visibility and brand click-through authority.

Build beautiful CSS gradients visually with a live preview. Adjust colours, angles, and stops, then copy the CSS code.
CSS Gradients in Modern Web Design
CSS gradients allow you to display smooth colour transitions without loading a single image file. Unlike background images, gradients are rendered by the browser's GPU at any resolution, so they always appear sharp on Retina displays and never increase your page load time. They are a core design primitive that every professional frontend developer needs.
Linear gradients create straight colour flows along an angle (e.g., top to bottom or diagonally). Radial gradients create circular colour flows expanding from a centre point. Both types accept unlimited colour stops, enabling complex, multi-layered effects that rival Photoshop output while remaining fully scalable, editable, and responsive.
Design custom box shadows with visual sliders. Adjust offset, blur, spread, and colour for the perfect shadow effect.
Box Shadows in UI Design
Box shadows create depth and hierarchy in flat user interfaces. A well-placed shadow can make a card feel elevated, a button feel pressable, or a modal feel layered above the content behind it. The CSS box-shadow property accepts five values: horizontal offset, vertical offset, blur radius, spread radius, and colour — each of which affects the visual weight differently.
Modern design trends favour very subtle, diffused shadows (large blur, low opacity) rather than hard, dark drop shadows. Material Design, Apple's Human Interface Guidelines, and most premium SaaS products use soft elevation shadows to create visual layering without harsh edges.
Check if your text and background colour combination meets WCAG 2.1 accessibility standards for AA and AAA compliance.
Why Colour Contrast Matters for Accessibility
Web Content Accessibility Guidelines (WCAG) 2.1 define minimum contrast ratios between text and its background to ensure readability for people with low vision or colour deficiencies. Approximately 1 in 12 men and 1 in 200 women have some form of colour vision deficiency, making contrast compliance critical for inclusive design.
WCAG defines two conformance levels: AA (minimum) requires a 4.5:1 ratio for normal text and 3:1 for large text (18px+ or 14px+ bold). AAA (enhanced) requires 7:1 for normal and 4.5:1 for large text. Many countries, including the UK (Equality Act 2010) and the EU (European Accessibility Act), now legally require WCAG AA compliance for public-facing websites.
