STYLE HTML ELEMENTS WITH SPECIFIC ATTRIBUTES


Style HTML Elements With Specific Attributes


It is possible to style HTML elements that have specific attributes, not just class and id.
Note: IE7 and IE8 support attribute selectors only if a !DOCTYPE is specified. Attribute selection is NOT supported in IE6 and lower.

Attribute Selector

The example below styles all elements with a title attribute:


Example

[title]
{
color:blue;
}


Attribute and Value Selector


The example below styles all elements with title="W3Schools":


Example

[title=W3Schools]
{
border:5px solid green;
}



Attribute and Value Selector - Multiple Values


The example below styles all elements with a title attribute that contains a specified value. This works even if the attribute has space separated values:


Example

[title~=hello] { color:blue; }

The example below styles all elements with a lang attribute that contains a specified value. This works even if the attribute has hyphen ( - ) separated values:

Example

CSS::STYLING FORMS


Styling Forms

The attribute selectors are particularly useful for styling forms without class or ID:


Example

input[type="text"]
{
width:150px;
display:block;
margin-bottom:10px;
background-color:yellow;
}
input[type="button"]
{
width:120px;
margin-left:35px;
display:block;
}

CSS : FLOAT


CSS Float?




With CSS float, an element can be pushed to the left or right, allowing other elements to wrap around it.
Float is very often used for images, but it is also useful when working with layouts.


How Elements Float
Elements are floated horizontally, this means that an element can only be floated left or right, not up or down.
A floated element will move as far to the left or right as it can. Usually this means all the way to the left or right of the containing element.
The elements after the floating element will flow around it.
The elements before the floating element will not be affected.
If an image is floated to the right, a following text flows around it, to the left:

Example

img
{
float:right;
}


Floating Elements Next to Each Other

If you place several floating elements after each other, they will float next to each other if there is room.

Here we have made an image gallery using the float property:

Example

.thumbnail 
{
float:left;
width:110px;
height:90px;
margin:5px;
}


Turning off Float - Using Clear
Elements after the floating element will flow around it. To avoid this, use the clear property.
The clear property specifies which sides of an element other floating elements are not allowed.
Add a text line into the image gallery, using the clear property:

Example

.text_line
{
clear:both;
}

The number in the "CSS" column indicates in which CSS version the property is defined (CSS1 or CSS2).

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.
