Study Notes
CSS Fundamentals
- CSS (Cascading Style Sheets) defines a web page's design, separating it from HTML's content.
- HTML defines content, while CSS defines how that content is displayed.
- CSS uses a separate language from HTML, leveraging selectors to target specific HTML elements (e.g., headings, sidebars).
- CSS properties, like HTML attributes, are key-value pairs defining presentation.
- CSS files have a .css extension and store styles in rules. Each rule begins with a selector and includes a declaration block containing properties.
- The
colorproperty controls text color (e.g.,#FF0000is red). -
background-colorcontrols the background color. - Stylesheets are linked to HTML documents via the
<link>element (within<head>). - The
relattribute specifies the relationship as "stylesheet", and thehrefattribute points to the .css file.
CSS Syntax and Linking
- CSS rules have a selector followed by a declaration block within curly braces.
- Properties, like
color, are defined within the declaration block and control the visual aspects of the selected HTML elements. - Semicolons are crucial in separating declarations within a style block.
- Comments use
/* */syntax.
Units of Measurement
- CSS properties often require units (e.g., pixels (px), ems (em)).
-
emunits are relative to the element's font size, aiding in scaling across different font sizes. - A base font size can be established in CSS affecting other elements defined in em units.
Multiple Selectors
- Commas separate multiple HTML elements within a single selector for applying consistent styles.
-
font-familyallows for specifying fonts, considering different user installations. (e.g., "Helvetica", "Arial", sans-serif).
list-style-type
- The
list-style-typeproperty alters the bullet icon in<ul>elements. -
noneeliminates bullet points (used for e.g. navigation menus)
Reusing Styles
-
<link>elements in different HTML files let you reuse the same CSS styles. Linking all pages to one stylesheet ensures consistency. - Root relative paths for global stylesheets assist in managing dependencies in nested pages.
Text Formatting
-
text-decoration: Adds underlines or strike-throughs (e.g.,none,underline,line-through). -
text-align: Controls text alignment (left,right,center,justify). -
font-weight: Controls boldness (normal,bold). -
font-style: Controls italics (normal,italic).
CSS Hierarchy
- CSS rules cascade from various sources.
- External stylesheets have the lowest precedence while inline styles are prioritized.
Page-Specific Styles (<style> elements)
- Page-specific styles are incorporated into individual HTML files using the
<style>element within thehead. - The
styleelement overrides rules from external styles in the same scope. - Avoid page-specific styles due to maintenance complexity in larger projects.
Inline Styles (style attribute)
- Directly embedding CSS rules into HTML elements with the
styleattribute. - Inline styles have the highest precedence & are not advised for large projects
Multiple Stylesheets
- Several external stylesheets can be referenced, providing flexibility for managing large-scale styles.
- Order matters in style sheets; later files override earlier ones (e.g., global (
styles.css) and specific (product.css)).
