HTML body bgcolor transparent

问题

I have this HTML

<html>
<head>
</head>
<body bgcolor="#FFFFFF" 
style="margin:0px;padding:0px;" 
<div style=width:100%;color:#000000;padding:25px;font-family: Segoe UI;font-size: 17px;"></div></body></html>

Here i have set bgcolor="#FFFFFF" but i want it to be transparent how to do it ?

回答1:

HTML provides no means to specify a transparent background (and the means it has to specify backgrounds of any kind are obsolete and should not be used). You can do this in CSS.

body { 
    background-color: transparent;
}

This will make the background of the <html> element visible.

There is no way to make the browser window transparent.

回答2:

With inline-styling you can achieve this with:

<body style="background-color: transparent;">

But a better option is to put the following code:

body { background-color:transparent; }

in a CSS file which you link to in the <head> section of the page like so:

<link rel="stylesheet" type="text/css" href="NAMEOFFILE.css">

回答3:

background-color: transparent;

Update
However, you HAVE NO WAY to make the browser window transparent. So, even if you use the code above, your background will still be white.

回答4:

You need to use CSS instead of HTML attributes to set transparent background:

<body style="background: transparent; margin: 0; padding: 0;">

Preferably you should have a style sheet for the page where you put the styles instead of putting styles in the HTML elements.

Note: To have an iframe with a transparent background (which is the only way that a transparent background on a page can be used) you need to add the allowtransparency attribute to the iframe tag for it to work in IE:

<iframe .... allowtransparency="true"></iframe>

回答5:

body {

    background-color: rgba(255, 255, 255, 0.5)
};

last value is alpha - it will set transparency values between 0 and 1; 0 transparent;
