Set CSS attributes in Javascript

1. Transparency:

If you do not specify a background color or a background image for a text, the background of this element is usually transparent.

This is important, if an absolutely positioned element with text is placed on a text element, it will be very confusing. Then we can set a background image or background color to cover it, if necessary, you can set it to transparent " (transparent)

General settings for Transparent Elements CSS as follows:

opacity: . 75 ; /// FF new

- Moz - opacity :. 75 ; // Transparency for older extends illas

filter: alpha (opacity = 75 ); // for IE

2. CSS with a hyphen:

 

Camel naming:

Element. style. fontfamily="Sans-Serif ";

Element. style. borderleftwidth="5px ";

Element. style. zindex= 100;

 

3 Note:

Code VaR Padding_left =   50 ;
Element. style. Left = Padding_left + "PX "; // Do not forget to add units

VaR Topmargin =   10 , Rigntmargin =   11 , Bottommargin =   12 , Leftmargin =   13 ;
Element. style. Margin = Topmargin + "PX" + Rigntmargin + "PX" + Bottommargin + "PX" + Leftmargin + "PX ";

4. Set float

Element.style.css float = "Left "; // Firefox Chrome Opera
Element. style. stylefloat = "Left "; // IE
