Study Notes
HTML5 Attributes
- Attributes are extra data for HTML elements, adding context and functionality.
- Attributes are always written inside the opening tag of an element.
- Attributes are key-value pairs (name=value), with values in double quotes.
- Attributes control elements' appearance, behavior, and accessibility.
Key HTML5 Attributes
-
hrefattribute: Used with the<a>tag to define the link's URL. -
srcattribute: Used with the<img>tag to specify the image file's URL. -
altattribute: Used with<img>to offer alternative text for images (accessibility). -
widthandheightattributes: Used with<img>to set image dimensions. -
styleattribute: Used for inline CSS styling. -
langattribute: Indicates the language of the content. -
titleattribute: Provides a tooltip description when hovering over an element. -
valueattribute: Sets default values for form elements like<input>and<textarea>.
Best Practices for Attributes
- Attribute names should be lowercase.
- Values should be enclosed in double quotes, not single quotes.
- Avoid unused or outdated attributes.
- Choose the right attributes for the HTML element.
Understanding the style attribute
- The
styleattribute uses CSS properties and values to style elements. - Properties define visual aspects (color, size, font).
- Values set the property's specific settings.
- Properties are separated by colons (:) and multiple properties by semicolons (;).
Importance of Attribute Values
- Ensure attribute values are correct and complete.
- Use appropriate data formats.
- Avoid spaces in values unless enclosed in double quotes.
- Correct placement and formatting are crucial.
title Attribute for Element Description
- The
titleattribute displays a tooltip when mousing over an element. - This tooltip gives more information to the user.
HTML Tags and Attributes
- Single quotes can be used inside double quotes and vice versa for attributes.
- Values are enclosed in double quotes. Single quotes are for specific parts of a value.
HTML Element Styles
- The
styleattribute is used to apply CSS styles to elements. - The syntax is
element style="property: value;"(e.g.,h1 style="color:red;").
CSS Properties and Values
-
font-family: Specifies the font. -
font-size: Sets the text size. -
font-weight: Determines text boldness (like bold or normal). -
text-align: Aligns text (left, right, center). -
background-color: Sets element background color.
CSS Example
- The provided example was incomplete.
Inline Styles vs. External Stylesheets
- Inline styles are applied directly within HTML elements using the
styleattribute. - CSS styles can be applied to multiple elements through the
styleattribute. - External stylesheets (
.cssfiles) provide a better way to style many pages, ensuring consistency.
CSS Specificity
- Inline styles have the highest specificity and take precedence.
- External stylesheets have the lowest specificity.
Understanding CSS Prioritization
- CSS styles are applied based on specificity.
- Styles with higher specificity override others.
- Prioritization factors include: inline styles > internal stylesheets > external stylesheets.
CSS Prioritization Illustration
- If inline style specifies blue text, but an external style specifies red, the element displays blue text.
Additional Tips for CSS Styles
- Semicolons separate CSS properties.
- External stylesheets are recommended for larger projects.
- Consider CSS preprocessors for advanced projects.
