我的媒体查询是否正确

Question

我想知道是否有人可以告诉我我的媒体查询是否正确。 我是网页设计的新手，正在上一门课程。我必须使我的网站具有响应性并在今晚提交，但我真的很努力。我花了数小时研究和更改事物，但是由于某些原因，我的查询似乎不适用于某些事物。

这些是我到目前为止所做的

/*media queries*/

/*768px*/




@media only screen and (min-width: 768px)and(max-width:1024){
.tm-logo{   
align-items: center;}    
}

@media only screen and (min-width: 768px)and(max-width:1024){
.tm-nav ul li a{
padding: 20px 30px;
text-decoration: none;}

}

@media only screen and (min-width: 768px)and(max-width:1024){
.tm-nav ul li{
display: inline-block;
background-color: #80c625;
padding: 10px;
}
}


@media only screen and (min-width: 768px)and(max-width:1024){
.divTableBody {
padding: 5px;
align-content: center;}
}


@media only screen and (min-width: 768px)and(max-width:1024){

}

@media only screen and (min-width: 768px)and(max-width:1024){

align-items: center;}

}

@media only screen and (min-width: 768px)and(max-width:1024){
    .whybody img{
        float: none;
        align-items: center;}
}


@media only screen and (min-width: 768px)and(max-width:1024){
.why-logo{ text-align: center;
    }

    }
/******480px*****/

@media only screen and (min-width:320px)and(max-width:480px){
    .wish{width:100%;
    float:none;
    align-items: center;}
}


@media only screen and (min-width:320px)and(max-width:480px){

.tm-logo{
       align-items: center;}
}

@media only screen and (min-width:320px)and(max-width:480px){
.tm-nav ul li{
    display: inline-block;
     background-color: #80c625;
    padding: 10px;
    align-content: center;
    }
}

 @media only screen and (min-width:320px)and(max-width:480px){   
.divTableBody {
        padding: 5px;
        margin: 5%;}
}


@media only screen and (min-width:320px)and(max-width:480px){
.more{
    align-items: center;}
}

@media only screen and (min-width:320px)and(max-width:480px){
    .whybody img{
        align-items: center;
    float: none;}
}

@media only screen and (min-width:320px)and(max-width:480px){
.why-logo{ text-align: center;
    }

    }

/********footer*******/
@media (max-width: 600px) {

    .footer-distributed .footer-left,
    .footer-distributed .footer-right{
        text-align: center;
    }

.footer-distributed .footer-right{
    float: none;
    margin: 0 auto 20px;
}

.footer-distributed .footer-left p.footer-links{
    line-height: 1.8;
}
}

这是我的CSS：

    /*default page style*/


    body{
    display: block;
    background-color: #eeeeee;
    font-family: 'Open Sans', sans-serif;

老实说，我本可以准备完整的球，我知道是否应该从头开始重做大部分，但是我必须至少在今天晚上之前提交一些内容。希望有人可以帮助我！ 谢谢！

Answer 1

使用媒体查询时，您可以将所需的所有代码堆叠到不同的屏幕尺寸，并按以下方式一起使用：

@media only screen and (min-width:768px) and (max-width:1024px) {
   .tm-logo{   
      align-items: center;
   } 

   .tm-nav ul li a{
      padding: 20px 30px;
      text-decoration: none;
   }

   .tm-nav ul li{
      display: inline-block;
      background-color: #80c625;
      padding: 10px;
   }

   .divTableBody {
      padding: 5px;
      align-content: center;
   }

   .more {
      align-items: center;
   }

   .wish {
      width:100%;
      float:none;
      align-items: center;
   }

   .whybody img{
      float: none;
      align-items: center;
   }

   .why-logo { 
      text-align: center;
    }
}

这是您的第一个查询，您可以对其他两个查询执行相同的操作。

Answer 2

    @media only screen and (min-width: 768px)and(max-width:1024px) {
  .tm-logo {
    align-items: center;
  }
  .tm-nav ul li a {
    padding: 20px 30px;
    text-decoration: none;
  }
  .tm-nav ul li {
    display: inline-block;
    background-color: #80c625;
    padding: 10px;
  }
  .divTableBody {
    padding: 5px;
    align-content: center;
  }
  .more {
    align-items: center;
  }
  .wish {
    width: 100%;
    float: none;
    align-items: center;
  }
  .whybody img {
    float: none;
    align-items: center;
  }
  .why-logo {
    text-align: center;
  }
  /******480px*****/
  @media only screen and (min-width:320px)and(max-width:480px) {
    .wish {
      width: 100%;
      float: none;
      align-items: center;
    }
    .tm-logo {
      align-items: center;
    }
    .tm-nav ul li {
      display: inline-block;
      background-color: #80c625;
      padding: 10px;
      align-content: center;
    }
    .divTableBody {
      padding: 5px;
      margin: 5%;
    }
    .more {
      align-items: center;
    }
    .whybody img {
      align-items: center;
      float: none;
    }
    .why-logo {
      text-align: center;
    }
    /********footer*******/
    @media only screen and (max-width: 600px) {
      .footer-distributed .footer-left,
      .footer-distributed .footer-right {
        text-align: center;
      }
      .footer-distributed .footer-right {
        float: none;
        margin: 0 auto 20px;
      }
      .footer-distributed .footer-left p.footer-links {
        line-height: 1.8;
      }
    }

您可以执行此操作。测量宽度是媒体查询的一个很好的实际示例，但并不是唯一可用的方法。您在1024年之后没有提到 px ，也无需重新声明 @media only屏幕以及（min-width：768px）和（max-width：1024px）一次又一次：）
