فهم ألوان ووحدات CSS
تنسيقات الألوان HEX و RGB و HSL
يدعم CSS عدة تنسيقات ألوان.
<strong>RGB</strong> يستخدم قيماً عشرية من 0 إلى 255.
<strong>HSL</strong> هو الأكثر بديهية للمصممين.
CSS Named Colors
CSS provides 147 named colors like coral, steelblue, and rebeccapurple. While convenient for prototyping, named colors offer limited precision. Converting a CSS color name to HEX or RGB gives you exact values you can fine-tune for production use.
CMYK للطباعة
<strong>CMYK</strong> هو نموذج الألوان القياسي للطباعة.
HSV في أدوات التصميم
<strong>HSV</strong> هو نموذج الألوان الأصلي في Photoshop وFigma وSketch.
PX مقابل REM: شرح وحدات CSS
<strong>البكسل (PX)</strong> وحدات مطلقة.
اقسم البكسل على 16 للحصول على قيم REM.
<strong>وحدات EM</strong> نسبية لحجم خط العنصر الأب وليس الجذر.
- 1rem = 16px (default browser setting)
- 1em = parent font-size (context-dependent)
- 0.75rem = 12px — common for small/caption text
- 1.25rem = 20px — common for subheadings
- 2rem = 32px — common for section headings
لماذا تستخدم محولات CSS؟
التحويل اليدوي مرهق وعرضة للأخطاء.
- Instant results — paste a value and get the converted output immediately, no formulas needed.
- Copy-ready output — every result includes a one-click copy button with properly formatted CSS syntax.
- Color preview — see a live swatch of the converted color to visually confirm accuracy.
- No installation — works in any browser, on any device. No extensions, downloads, or signups.
- Developer-friendly — shareable URLs with pre-filled values for easy team collaboration.
Common CSS Conversion Workflows
- Design handoff: Figma and Sketch export colors as HEX. Convert to RGB or HSL if your codebase uses those formats.
- Dark mode generation: Take your light-mode HSL palette, adjust lightness values, and convert back to HEX.
- Accessibility checks: Convert colors to RGB to calculate contrast ratios using the WCAG luminance formula.
- Legacy migration: Convert pixel-based layouts to rem-based responsive systems during refactors.
- Cross-browser debugging: Quickly convert colors to match your source code format.
