how to override the background when using float element-CodePudding

I have a website footer, this is the code looks like:

<div className="App-footer-float">
  <div id="footer" className="App-footer">
    <Divider></Divider>
    <div>
      <Row justify="center" align="middle">
        <Col>
          <div>© 2022 Apple</div>
          <div>ICP 1700232-6</div>
        </Col>
      </Row>
    </div>
  </div>
</div>

this is the css looks like:

.App-footer-float{
  margin: 0 auto;
  width: 100%;
}

.App-footer{
  font-size: 0.3rem;
  position: fixed;
  bottom: 0;
  text-align: "center";
  width: 100%;
}

this footer element are transparent, now I want to using the float element to override the background element. I have tried to set the background color in App-footer-float:

.App-footer-float{
  margin: 0 auto;
  width: 100%;
  background-color:red;
}

also tried to set the opacity and transparent, seems could not work. what should I do to make the footer element override the background and make it non-transparent?

CodePudding user response：

To override the background of a float element, you can use the background property in CSS. For example:

    .float-element {
  float: left;
  background: #000;
}

This will set the background color of the element to black. You can also use other values for the background property, such as a image URL or a color value in a different format (e.g. rgb(), hsl(), etc.).

If you want to override the background of the element that comes after the float element, you can use the clear property. For example:

  .float-element {
  float: left;
  background: #000;
}

.next-element {
  clear: both;
  background: #fff;
}

This will set the background color of the element after the float element to white, which will override the background of the float element.

It's important to note that the clear property only works for elements that come after the float element, not elements that come before it. If you want to override the background of an element that comes before the float element, you can use the overflow property instead. For example:

    .prev-element {
  overflow: hidden;
  background: #fff;
}

.float-element {
  float: left;
  background: #000;
}

This will set the background color of the element before the float element to white, which will override the background of the float element.
