There is no hex code for transparency. For CSS, you can use either transparentor rgba(0, 0, 0, 0).
没有透明度的十六进制代码。对于 CSS，您可以使用transparent或rgba(0, 0, 0, 0)。

Or you could just put
或者你可以把
background-color: rgba(0,0,0,0.0);
That should solve your problem.
那应该可以解决您的问题。

Simply choose your background color of your item and specify the opacity separatly:
只需选择项目的背景颜色并单独指定不透明度：
div { background-color:#000; opacity:0.8; }

There is no transparency component of the color hex string. There is opacity, which is a float from 0.0 to 1.0.
颜色十六进制字符串没有透明度组件。有opacity，它是从 0.0 到 1.0 的浮点数。

try using
尝试使用
background-color: none;

这对我有用。

jus add two zeroes (00) before your color code you will get the transparent of that color
只需在颜色代码之前添加两个零 (00)，您将获得该颜色的透明

There are now 8-digit hex codes in CSS4 (CSS Color Module Level 4), the last two digit (or in case of the abbreviation, the last of the 4 digits) represents alpha, 00meaning fully transparent and ffmeaning fully opaque, 7frepresenting an opacity of 0.5 etc.
CSS4 中现在有 8 位十六进制代码（CSS Color Module Level 4），最后两位数字（或者在缩写的情况下，4 位数字中的最后一位）代表 alpha，00表示完全透明，ff表示完全不透明，7f代表一个不透明度为 0.5 等
The format is '#rrggbbaa'or the shorthand, '#rgba'.
格式是'#rrggbbaa'或简写，'#rgba'.
Support is lacking for MS browsers, they might be less cooperative or just slower than the other developers, either or both of which actually sealed IE's fate: https://caniuse.com/#feat=css-rrggbbaa
缺乏对 MS 浏览器的支持，他们可能比其他开发人员合作得更少或只是速度慢，这两者实际上决定了 IE 的命运：https: //caniuse.com/#feat=css-rrggbbaa

Simply put:
简单的说：
.democlass {
background-color: rgba(246,245,245,0);
}
That should give you a transparent background.
这应该给你一个透明的背景。
