css
Lists
- Lists are vertical by default
- Horizontal lists
- ul {
list-style-type: none;
margin: 0;
padding: 0;
}
li {
display: inline;
}
Box-sizing
- Adding padding and borders will stretch
an element beyond the specified width - box-sizing: border-box;
-
The padding and border no longer increase
the width - box-sizing:
- -moz-box-sizing:
Position
- Static positioning
- Elements are positioned static by default
(according to normal flow of the page) - Fixed positioning
- Element with fixed position relative to the
browser window - position: fixed;
- top: 30px;
- right: 5px;
- Relative positioning
- Element is positioned relative to its normal
position - position: relative;
- left: -20px;
Position
- Absolute positioning
- Element is positioned relative to the first parent
element that has a position other than static - position: absolute;
- left: 100px;
- top: 150px;
- Overlapping elements
-
z-index property specifies the stack order of
an element - z-index: -1;
Float
- clear property
- Excludes the element from floating
elements around it - clear: both;
- clear: left;
- Clear elements floated to the left
- clear: right;
- Clear elements floated to the right
Vertical Alignment
- Vertical control limitations
- Horizontal placement is generally easy to
control - "Vertical placement is frequently unintuitive,
convoluted, or outright impossible" - A way to work around it
- .cdiv {
margin: auto;
position: absolute;
top: 0; bottom: 0; left: 0; right: 0;
}
Animations
- It is possible to animate elements without using
Flash or JavaScript - Keyframes
- The @keyframes rule is where the animation
is created - Specify a CSS style inside the @keyframes rule
and the animation will gradually change from
the current style to the new style - @keyframes
- @-webkit-keyframes
- Chrome and Safari
Animations
Example
-
@-webkit-keyframes squarechange {
from { background: green; }
to { background: red; }
}
#square {
height: 100px;
width: 100px;
animation: squarechange 5s;
-webkit-animation: squarechange 5s;
} -
