CSS : Hiding an Element - display:none or visibility:hidden

Hiding an Element - display:none or visibility:hidden

Hiding an element can be done by setting the display property to "none" or the visibility property to "hidden". However, notice that these two methods produce different results:
visibility:hidden hides an element, but it will still take up the same space as before. The element will be hidden, but still affect the layout.


Example

h1.hidden {visibility:hidden;}

display:none hides an element, and it will not take up any space. The element will be hidden, and the page will be displayed as if the element is not there:


Example

h1.hidden {display:none;}

CSS : Display - Block and Inline Elements

CSS Display - Block and Inline Elements

A block element is an element that takes up the full width available, and has a line break before and after it.
Examples of block elements:
  • <h1>
  • <p>
  • <div>
An inline element only takes up as much width as necessary, and does not force line breaks.
Examples of inline elements:
  • <span>
  • <a>

CSS : LEFT & RIGHT ALIGNING BY POSITION PROPERTY


Left and Right Aligning Using the position Property

One method of aligning elements is to use absolute positioning:

Example

.right
{
position:absolute;
right:0px;
width:300px;
background-color:#b0e0e6;
}

HINT: Absolute positioned elements are removed from the normal flow, and can overlap elements.


Crossbrowser Compatibility Issues

When aligning elements like this, it is always a good idea to predefine margin and padding for the <body> element. This is to avoid visual differences in different browsers.
There is a problem with IE8 and earlier, when using the position property. If a container element (in our case <div class="container">) has a specified width, and the !DOCTYPE declaration is missing, IE8 and earlier versions will add a 17px margin on the right side. This seems to be space reserved for a scrollbar. Always set the !DOCTYPE declaration when using the position property:


Example

body
{
margin:0;
padding:0;
}
.container
{
position:relative;
width:100%;
}
.right
{
position:absolute;
right:0px;
width:300px;
background-color:#b0e0e6;
}

CSS : OVERLAPPING ELEMENTS

Overlapping Elements


When elements are positioned outside the normal flow, they can overlap other elements.
The z-index property specifies the stack order of an element (which element should be placed in front of, or behind, the others).
An element can have a positive or negative stack order:


Example

img
{
position:absolute;
left:0px;
top:0px;
z-index:-1;
}

An element with greater stack order is always in front of an element with a lower stack order.
HINT: If two positioned elements overlap, without a z-index specified, the element positioned last in the HTML code will be shown on top.

CSS : CHANGING HOW AN ELEMENT IS VIEWED OR DISPLAYED

Changing How an Element is Displayed
Changing an inline element to a block element, or vice versa, can be useful for making the page look a specific way, and still follow web standards.
The following example displays list items as inline elements:


Example

li {display:inline;}

The following example displays span elements as block elements:


Example

span {display:block;}
Note: Changing the display type of an element changes only how the element is displayed, NOT what kind of element it is. For example: An inline element set to display:block is not allowed to have a block element nested inside of it.

CSS : FIXED POSITIONING

Fixed Positioning

An element with fixed position is positioned relative to the browser window.
It will not move even if the window is scrolled:

Example

p.pos_fixed
{
position:fixed;
top:30px;
right:5px;
}

HINT: IE7 and IE8 support the fixed value only if a !DOCTYPE is specified.
Fixed positioned elements are removed from the normal flow. The document and other elements behave like the fixed positioned element does not exist.
Fixed positioned elements can overlap other elements.

CSS : ABSOLUTE POSITIONING

Absolute Positioning


An absolute position element is positioned relative to the first parent element that has a position other than static. If no such element is found, the containing block is <html>:


Example

h2
{
position:absolute;
left:100px;
top:150px;
}

Absolutely positioned elements are removed from the normal flow. The document and other elements behave like the absolutely positioned element does not exist. Absolutely positioned elements can overlap other elements.
