    Study Notes

    CSS Grid Layout

    • CSS Grid Layout is a two-dimensional grid-based layout system.
    • Rows and columns are defined in CSS, not HTML.
    • Useful for creating flexible layouts like galleries and newspapers.

    Creating a Grid Container

    • To create a grid container, set the element's display property to grid (container becomes a block element) or inline-grid (container becomes an inline element).
    • The height of a grid parent can grow/shrink.

    Grid Items

    • background: #ffcc00;
    • border: 2px solid black;
    • padding: 10px;

    Adding Columns

    • grid-template-columns property is used to add more columns.
    • Can use percentage values (25% 75%) or fr (fraction) units (1fr 3fr).
    • fr-based columns are flexible—they won't shrink below their minimum content size.

    Grid Areas

    • Can name areas of the grid with grid-template-areas.
    • This makes layouts more structured & easier to manage.

    Minmax

    • minmax(min, max) function specifies the minimum and maximum width/height of a column/row.
    • It can be useful for adjusting layouts depending on how available space.

    Auto-Fill/Auto-Fit

    • auto-fill keyword automatically creates as many grid tracks (rows or columns) as will fit within the container.
    • If there's extra space, it adds empty tracks.
    • auto-fit keyword adjusts the grid items so they fill the available space.

    Aligning Items

    • justify-content, justify-items, align-content, align-items are used to align items within grid containers horizontally or vertically.
    • Similar options found in flexbox.
    • Useful for controlling the alignment of a specific grid child using justify-self or align-self.

    Aspect Ratio Properties

    • The aspect ratio of the image can be set using aspect-ratio (width/height ratio).

    Screen Resolution

    • Resolution is the number of pixels displayed on a screen (width x height).
    • Higher resolution = sharper images/text.
    • Common resolutions include 1920x1080(Full HD), 2560x1440(WQHD), 3840x2160(Ultra HD), etc.
    • Aspect ratio describes the proportion between width and height.

    Responsive Web Design

    • Websites must adjust to different screen sizes.
    • Using vw (viewport width), and vh (viewport height) units allows for responsive design in CSS.
    • media queries are used to adjust styles based on viewport dimensions and device type.

    Creating a hero section (100vh)

    • Responsive design is a technique to adapt to different screen sizes, using techniques like viewport, aspect ratio, resolution, screen width/height.

    Animations and Transitions

    • Animations in CSS create changes over time using keyframes.
    • Transitions handle smooth shifts between two states. Use transition properties to create smooth transitions.
    • transform property is used for animations; changes to elements' appearance (e.g., rotation, scaling, moving).
    • will-change property lets the browser optimize for the animation.

    Keyframe Animations

    • Keyframe animations create smooth transitions between multiple steps that use percentages.
    • Keyword from is equivalent to 0% and to is equivalent to 100%. Adding more % in the animation allows for more steps/frames between the beginning and end of the animation.

    Timing Functions

    • Timing functions control the speed and acceleration of an animation.
    • linear timing function animates an element at a consistent speed throughout the animation.
    • Other timing functions like ease-in, ease-out, ease-in-out allow for slower/faster speed throughout animation.

    CSS Variables

    • CSS variables (often called custom properties) allow for efficient code by making updates in one place (defining the value of the variable), which will propagate through the document.
    • Two types include global variables (scoped to the :root element) and local variables (scoped to a specific selector).
    • Last defined wins property/variable: If two rules define the same variable, the last to be declared takes precedence.
