CSS Box Model

Content (Blue)

  • The area that contains your text or some other visual element
  • By default, height and width are not specified so the area is as big as what it contains
  • Using the following CSS properties, we can manipulate the dimensions of an element
    • height, min-height, max-height
    • width, min-width, max-width

CSS Box Model

Padding (Green)

  • The space between the content and the border (inner space)
  • Using the following CSS properties, we can manipulate the padding of an element:
    • padding-top, padding-right, padding-bottom, padding-left
    • Shorthand:
      • padding: <top>, <right>, <bottom>, <left>
      • padding: <top>, <horizontal>, <bottom>
      • padding: <vertical>, <horizontal>

CSS Box Model

Border (Yellow)

  • The outline around an element
  • Using the following CSS properties, we can manipulate the border:
    • border-width: 2px;
    • border-style: solid;
    • border-color: #000000;
    • Shorthand:
      • border: <width> <style> <color>;

Margin (Orange)

  • The space around an element (outer space)
  • Using the following CSS properties, we can manipulate the padding of an element:
    • margin-top, margin-right, margin-bottom, margin-left
    • Shorthand:
      • margin: <top>, <right>, <bottom>, <left>
      • margin: <top>, <horizontal>, <bottom>
