CSS properties can also be dynamically changed with a JavaScript.

Scripting Syntax: object.style.visibility=”hidden”

In our HTML DOM tutorial you can find more details about the visibility property.

In our HTML DOM tutorial you can also find a full Style Object Reference.

Example

p
{
visibility: hidden
}

Possible Values

Value Description
visible The element is visible
hidden The element is invisible
collapse When used in table elements, this value removes a row or column, but it does not affect the table layout. The space taken up by the row or column will be available for other content. If this value is used on other elements, it renders as “hidden”

css and email: how to do it

Leave a reply

I’ve been having problem applying css on email. I almost wanted to sleep but bumping on these articles awoke my senses.

You will find tips and guidelines on these urls so please read them for their explanations on how to code html css driven for your emails:

Bottom line just remember these things I got it from the webreference.com

Do …

  • Use inline style declarations for the most important styles.
  • Declare styles in a style tag when they’re not absolutely necessary.
  • Use table tags for multi-column layouts and floating elements.
  • Test your email in multiple standalone and Web-based email clients.

Don’t …

  • Use external stylesheets.
  • Use floating div tags for multi-column layouts.
  • Expect CSS background images to show up in most email clients.
  • Rely on images showing up, especially background images.

Now, I can sleep :P

css: opacity

Leave a reply

There’s an interesting site where you can use as a reference for opacity. You can check it here => http://www.mandarindesign.com/opacity.html

W3C SAYS
Opacity can be thought of conceptually as a postprocessing operation. Conceptually, after the element (including its children) is rendered into an RGBA offscreen image, the opacity setting specifies how to blend the offscreen rendering into the current composite rendering.

Name: 	        opacity
Value: 	        <alphavalue> | inherit
Initial: 	1
Applies to: 	all elements
Inherited: 	no
Percentages: 	N/A
Media: 	        visual
Computed value: The same as the specified
value after clipping the <alphavalue>
to the range [0.0,1.0].

<alphavalue>
Syntactically a <number>. The uniform opacity setting to be applied across an entire object. Any values outside the range 0.0 (fully transparent) to 1.0 (fully opaque) will be clamped to this range. If the object is a container element, then the effect is as if the contents of the container element were blended against the current background using a mask where the value of each pixel of the mask is <alphavalue>.

opacity 25 opacity 50 opacity 75 opacity 1.05

This example uses Mozilla proprietary code in conjunction with IE code. CSS3 is not fully defined as of today (August 2004). If you remove the -moz-opacity it will look like this.

Sample code:

fade{float:left;filter:alpha(opacity=100);-moz-opacity:1.0;opacity:1.0;}
