css box model

  • as far as a style sheet is concerned, everything in your HTML is inside a box
  • from the outside in it looks like this:
    this is some content
  • content: text & web page elements in the container
  • padding: area between the content and the margin
  • border: between the padding and the margin
  • margin: determines the empty space between the element and adjacent elements
  • content width vs. visible width:
    • content width is the size of the visible content (text, images, etc.)
    • visible width, however, includes everything out to the edges of border

float and display

Float property

Elements that seem to "float" on the right or left side of either the browser window or another element are often configured using the float property.

.floatright {float: right;}
<img src="file.jpg" class="floatright">

Display property

Configures how and if an element is displayed.

  • display:none;
    The element will not be displayed.
  • display:block ;
    The element is rendered as a block element, even if it is actually an inline element, such as a hyperlink.
  • display:inline;
    The element will be rendered as an inline element, even if it is actually a block element, such as a <li>.
