I. introduction to translucency of DIV CSS

Set the equipment DIV semi-transparent CSS code:

Div {filter:alpha (Opacity=80);-moz-opacity:0.5;opacity: 0.5;}

Note: 1. Filter: configure win IE with semi-clear filter attainments, filter:alpha (Opacity=80) represents the object 80% semi-clear, Firefox Reader does not recognize 2,-moz-opacity: mozilla firefox Firefox to achieve semi-colorless, win IE does not recognize this attribute,-moz-opacity:0.5 is equivalent to setting semi-colorless to 50% 3, opacity: for all hunting devices except IE, including Google, the end is mainly for google browser, opacity:0.5 Disclose the performance setting, equipment and equipment 50% and 50% of the equipment is half-clear.

In order to see the semi-transparent completion of DIV, we set up two DIV layers, leaving one in the other DIV layer, and the outer DIV is named ".div-a"; the layer CSS class trapped below is named ".div-b", which forms a ".div-b" box in ".div-a".

We configure a set for the underlying DIV is a picture, and the DIV box below sets the village color.

2. No semi-colorless pattern instance is configured.

1. According to the depicted example, the semi-colorless HTML source code is not set for equipment furnishings:

3. An example of configuring CSS translucent pattern for DIV

1. We intervene in the semi-colorless pattern code for ".div-b" selectors:

Filter:alpha (Opacity=60);-moz-opacity:0.6;opacity: 0.6

Configure 60% translucent score

The HTML code of the incomplete instance web page is as follows:

Filter:alpha (Opacity=60);-moz-opacity:0.6;opacity: 0.6}

/ * CSS interpretation makes it clear: the CSS code is wrapped here in order to make the code appear complete here, and the CSS results will not be affected after the line break * /

2. Take a screenshot of the reader effect:

Summary: according to the above two examples, the first one is not equipped with translucent equipment, and the other is configured with a translucent name to complete the semi-transparent function of the div layer, and everyone may adjust the semi-achromatic value to achieve the desired semi-achromatic value. Setting the semi-transparent effect of equipment should consider the compatibility of hunting devices such as IE browser, Google, Firefox and so on, so our translucent code must be broken.
