如何在不影响文本的情况下设置背景不透明度 [英] How to set a background opacity without affecting the text

问题描述

我基本上是在尝试创建此代码：

I am basically trying to create this:

添加了带有背景图片的父容器，然后是子容器需要透明。

Added a parent container with a background image,then a child container that needs to be transparent.

这里是我的HTML：

<div class="scent-brand-contact">
    <div class="scent-brand-container">               
       <section id="black-studio-tinymce-8" class="widget-1 widget-first widget-odd widget widget_black_studio_tinymce">
            <div class="textwidget">
                <p>All our fragrances are developed in compliance with the International Fragrance Association ensuring strict adherence to safety purity and manufacturing standards.</p>
                <p>LEARN MORE ABOUT HOW SCENT BRANDING CAN BENEFIT YOUR BUSINESS</p>
            </div>
        </section>
        <section id="text-4" class="widget-2 widget-last widget-even widget widget_text">
            <div class="textwidget">
            <button type="button">contact us today</button>
            </div>
        </section>                    
   </div>
</div>

和CSS：

.scent-brand-contact{
    position:relative;
    background-image: url(images/lemon.jpg);
    background-position: center center;
    background-attachment: fixed;
    background-size: cover;
    min-height:380px;
}
.scent-brand-container {
    background-color: #fff9c0;
    padding: 10px;
    opacity: 0.7;
    padding-top: 5%;
    margin: auto;
    position: absolute;
    top: 12%;
    width: 100%;
    min-height: 285px;
}

此刻，按钮和文本也正在得到不透明。
如何在不影响文本和按钮的情况下具有透明背景？

At the moment,it's happening that the button and the texts are also getting the opacity. How can I have the transparent background without affecting the text and the button?

推荐答案

您可以使用 rgba 仅使背景颜色透明，例如：

You can use rgba to make only the background color transparent, e.g.:

background: rgba(255, 249, 192, 0.7);
