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
andheight
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

margin

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 Radius
- The corner radius property is used to round the corners of an element's border

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.
