Exploring Web Design

In this chapter, we embark on a journey to develop a fresh perspective on web design. We'll learn how to differentiate between good and bad websites, applying objective rules to subjective elements. Key concepts will include critiquing websites, understanding audience communication, and the psychological impact of color use. We'll also delve into technical aspects of web images, exploring raster and vector formats, common file types, and their appropriate usage. This foundational knowledge will empower you to create well-designed, functional web pages.

  1. Exploring Web Design Chapter 1

  2. Objectives • Develop a new perspective of the WWW • Learn what makes a website good or bad • Discover how to apply objective rules to subjective matters • Begin to deconstruct the elements of a web page

  3. Perspective WWW is full of poorly designed webs Our pages can be well designed

  4. Critiquing Websites (1) • You are a web user • Watch for other people’s mistakes • Pay attention to what you like/dislike

  5. Critiquing Websites (2) • Questions to ask: • Do I like the way this site looks? • Can I tell what the site is about? • Does the design seem appropriate to what the site is about? • Can I find what I’m looking for easily?

  6. Critiquing Websites (3) • Don’t limit yourself to websites. Look at the layout and design of: • Newspapers • Magazines • Textbooks

  7. Consider Your Audience

  8. What is your message? • The WWW is a communication tool • Ask: • What message are you sending? • Will they understand the message? • How am I expressing the message?

  9. About Colors When viewing or creating websites ask: • How do the colors make me feel? • Can I read the text? • Are the colors loud or dull? (eye candy vs. bland corporate) • Do the colors look good together?

  10. Your Opinion You may have an opinion about a website. That’s great, but try to substantiate your likes/dislikes objectively using your training. Be specific!

  11. Getting Technical

  12. Web Color Limitations • 3 colors: Red, Green & Blue (RGB) • These three colors, in various combinations, are capable of creating millions of colors. • 216 colors in common between Windows and Macs • No longer an issue

  13. Raster Images (1) • JPEG, BMP, GIF, TIFF, PNG • Also called bitmapped images • Composed of pixels • Windows displays 96 dpi pixel resolution • Do NOT scale well

  14. Raster Images (2)

  15. Vector Images (1) • WMF, EWMF, SWF, PDF • Composed of dots and vectors • They scale well (enlarge) • Have independent resolution

  16. Dithering

  17. Common Web File Formats • JPEG • GIF • PNG • SWF • PDF

  18. JPEG • Joint Picture Experts Group • Lossy • Highly compressed • No transparency channel • 16.7 million colors • Used for photos and gradients

  19. GIF • Graphics Interchange Format • Lossless • Highly compressed • Have a transparency channel • 2 to 256 colors • Can cause banding in flesh tones/gradients • Used for logos and images with few colors

  20. PNG • Portable Network Graphics • Lossless • Highly compressed • Tranparency channel • Create raster and vector images • Still not used as widely and JPEG/GIF

  21. Animation • JPEG’s do not animate • GIF and PNG may be animated • Animation increases file size • Take longer to load • Use ONLY where appropriate to grab attention
