Study Notes
HTML Fundamentals
- The basic structure of an HTML document starts with the
<html>
element, which contains both the<head>
and<body>
elements. - The
<head>
section includes metadata, links to external stylesheets, and scripts, while the<body>
section holds the visible content of the webpage. - The
<!DOCTYPE>
declaration informs the browser which HTML version the document is using to ensure proper rendering of content. - HTML comments are written inside
<!-- comment text -->
and are not displayed by the browser. - The
<a>
tag (anchor tag) is used to create hyperlinks in HTML. Thehref
attribute specifies the destination URL. - The
src
(source) attribute is required in the<img>
tag and defines the location of the image file to be displayed on the webpage. - The
<meta charset="UTF-8">
tag specifies the character encoding for the webpage, enabling support for a variety of characters from different languages and symbols. - The
<h1>
tag represents the top-level heading in HTML and is the most prominent heading, often used for the main title or heading of a webpage. Headings from<h2>
to<h6>
decrease in size and importance. - The
<nav>
element is used to define a section of the webpage that contains navigation links, such as a menu or links to different sections of the site.
CSS Basics
- CSS (Cascading Style Sheets) is used to control the presentation and style of HTML documents.
- Internal CSS is placed within the
<style>
tag inside the<head>
of an HTML document. - External CSS is stored in a separate file with a
.css
extension and linked to an HTML document using the<link>
tag. - Inline CSS applies styles directly on an HTML element using the
style
attribute. - The
color
property sets the text color. - The
font-weight
property sets the weight of the font, wherebold
makes the text bold. - The
text-align
property sets the horizontal alignment of the text. - Inline CSS has higher specificity than external or internal styles. This means that if there is a conflict, inline styles will take precedence.
- The correct syntax for applying a class selector in CSS is to prefix the class name with a period (
.
), indicating that the styles should be applied to all elements with that class.
CSS Box Model
- The CSS box model consists of four components:
- Content: The actual content of the box (text, images, etc.).
- Padding: The space between the content and the border, which creates an inner space.
- Border: The edge around the padding (if any) and content, defining the box's outer edge.
- Margin: The space outside the border that separates the box from other elements.
- The
padding
property in CSS is used to create space between the content of an element and its border. - The
margin
property affects the space outside the border of an element, separating it from other elements. - The
border-width
property specifies the width (thickness) of the border around an element. - The
border-radius
property is used to create rounded corners on elements.
CSS Positioning
- The
position
property controls the positioning of an element. - The
static
positioning is the default, where elements flow normally in the document. - The
relative
positioning allows elements to be positioned relative to their normal position in the document flow. - The
absolute
positioning removes elements from the normal document flow and positions them relative to the nearest positioned ancestor. - The
fixed
positioning removes elements from the normal document flow and positions them relative to the browser window.
CSS Specificity and Inheritance
- CSS specificity determines which CSS rules are applied to an element when multiple rules could apply.
- Inline styles have the highest specificity, followed by IDs, classes, attributes, and then elements.
- Styles defined with an ID selector have a higher specificity than styles defined with a class selector.
CSS Flexbox and Grid
- Flexbox is designed to handle layout in one dimension, either horizontally (rows) or vertically (columns), making it easier to distribute space and align items within a container.
- The
gap
property (previously known asgrid-gap
in CSS Grid) defines the spacing between flex items. - The
align-items
property aligns flex items vertically within the flex container according to the specified alignment. - Flexbox is a one-dimensional layout model that allows items to be arranged in either a row or a column.
- The CSS Grid layout model allows for the creation of complex layouts in two dimensions, enabling designers to define both rows and columns within a container.
- The
grid-template-columns
property specifies the number of columns and their widths in a grid container.
CSS Animations and Transitions
- The
transition
property allows for smooth changes from one style to another over a specified duration. - CSS animations allow developers to create keyframe-based animations.
- Keyframes define the different stages of an animation, allowing for smooth movement and changes over time.
