    Study Notes

    CSS Boxes

    • Boxes in CSS are categorized as block or inline
    • Block boxes display on new lines
    • Inline boxes stay on the same line as other inline elements

    Block Boxes

    • Start on a new line
    • Respect width and height properties
    • Padding, margin, and border push other elements away if no explicit width is set, they stretch to fill their container

    Inline Boxes

    • Stay on the same line as other inline elements
    • Width and height properties don't apply
    • Top and bottom padding, margins, and borders won't push other elements away
    • Left and right padding, margins, and borders will push other inline elements away

    Display Property

    • Used to change the display type of an element
    • For example, changing the display type of a list item to block makes the item take up the full width of the line it is on

    Box Dimensions

    • By default, a box is sized just big enough to hold its contents
    • Use width and height properties to set custom dimensions
    • Possible units for box dimensions include pixels, rem, em, and percentages.

    Limiting Dimensions

    • min-width: Sets the smallest size a box can be when the window is narrow
    • max-width: Limits how wide a box can get when the window is wide, keeping content readable, especially on small screens

    Overflow Property

    • Controls how content that is too large to fit inside a box is handled
    • hidden: Hides extra content
    • visible: Shows any extra content
    • scroll: Adds a scrollbar
    • auto: Adds a scrollbar if the content is too big to fit

    Box Model

    • content: The actual content inside the box (text or images)
    • padding: The space between the content and the border
    • border: The visible boundary around the box
    • margin: The space outside the border

    Padding

    • The space between the box's content and its border
    • Values can be set for each side (top, right, bottom, left) or combined into a single value
    • padding: <value> <value> <value> <value> (top, right, bottom, left)
    • padding: <top> <right-left> <bottom> (top, right/left, bottom)
    • padding: <top-bottom> <right-left> (top-bottom, right-left)
    • padding: <value> (equal padding on all sides)

    Border

    • The visible boundary around the box
    • border-width: Sets the width of the border using units like px, em, rem, thin, medium, thick
    • border-style: Determines the style of the border (e.g., solid, dashed, dotted)
    • border-color: Sets the color of the border
    • Shorthand property can be used to set all border properties in one line

    Border Radius

    • The corner radius property is used to round the corners of an element's border
    • Can be set on all four corners separately or as a shorthand
    • Shapes like circles and ellipses can be created using border radius

    Margin

    • The space outside the border of a box. It creates distance between the box and adjacent elements or the page's edge.
    • Can be set for individual sides (top, right, bottom, left) or as a shorthand
    • Individual values like: margin-top: 10px; margin-right: 20px;
    • Shorthand values like: margin: 10px 20px 30px 40px; (top, right, bottom, left). Note that the order is still top, right, bottom, left.

    Default Margin

    • In many browsers, elements have default margin values. These values can vary between browsers.
    • margin: 0 value often used to remove default margins on elements and avoid spacing inconsistencies across different browsers.

    Aligning Content

    • auto unit within margins can be used to distribute available space between elements, centering them.
    • text-align: center can be used in order to center text inside an element, but this will not work for other content inside the container like Images.

    Box Sizing

    • box-sizing property controls how width, and height properties are calculated
    • content-box: The default, where width/height only include content. Padding, border, and margin are excluded
    • border-box: Width/height include padding, border, but not margin

    Display Behavior

    • display: block creates block-level elements, each starting on a new line, taking up the entire width available
    • display: inline creates inline elements, which flow within a line horizontally. Width isn't fixed
    • display: inline-block combines aspects of both, allowing width and height specifications, while staying on the same line.
    • display: none makes the element invisible, but the space it occupied is removed.

    Visibility

    • To hide an element without affecting layout, the visibility property can be used.
    • The element is hidden, but its space remains.
      • "hidden" hides the element but maintains space
      • "visible" shows the element

    Box Shadows

    • box-shadow: Creates a drop shadow effect around or inside an element
    • Multiple shadows can be defined, each with offset, blur radius, color, and position.
    • Use inset to place shadow inside the box.
