Study Notes

CSS Basics Introduction

  • CSS (Cascading Style Sheets) separate web site content from style.
  • XHTML files arrange content, while CSS handles presentation (fonts, colors, backgrounds, etc.)

Internal Stylesheet

  • CSS code placed within <head> tags of an XHTML file.
  • Each XHTML file contains the CSS code needed for its style. This means changes require editing each file accordingly.
  • Useful for single-page styling or when different pages have varying styles.
  • Example code included.

External Stylesheet

  • Separate CSS file (.css extension).
  • No (X)HTML in the file; only CSS code.
  • Link to the external CSS file in the <head> section of every XHTML file you want to style.
  • This makes it easier to maintain styles for multiple pages, because edits are only made to one file.
  • Example code included using <link> and @import methods.

Cascading Order

  • Inline styles (inside XHTML elements)
  • Internal stylesheets (inside <head> tags)
  • External stylesheets

Users with Disabilities

  • External stylesheets allow users with disabilities to customize the site by adjusting text size or color.
  • Users have different preferences.

Power Users

  • Stylesheets are beneficial for manipulating styles and reading web documents.
  • This is useful for web developers and advanced users who need to swap or change styles within the site.

Browser Issues

  • Different browsers will render and display CSS differently, so this must be considered and accounted for.
