这是我为@media 添加的代码:

 @media screen and (max-width:800px) {#background_grass, #Navbar, #logo, #NavLinks { width: 100%; } }

我做错了什么?我写的@Media 查询有误?

快速查看您的代码后,我建议您尝试这样的操作:

.games_image {
  height: 200px;
  margin: 25px 25px;
  margin-bottom: 25px;
  border-radius: 50px;
}

@media (max-width: 980px) {
.games_image {
  height: 200px;
  margin: 25px 25px;
  margin-bottom: 25px;
  border-radius: 50px;
}
}

另外我可能会包括这个:

* {
 width: 100%;
 padding: 0;
 margin: 0;
}

没有快速的方法来使用媒体查询并使其响应,但在下面包装媒体查询并对各个部分进行调整可以非常有效,并让您获得想要的效果。

从头开始构建时,您必须规划和构建 HTML 以使页面响应。您可以使用 Media Queries 使网页响应。然而,有大量屏幕和设备具有不同的高度和宽度,因此很难为每个设备创建一个准确的断点。对于初学者,您可以这样做:

*{
    margin: 0;
    padding: 0;
}

/* Small devices (portrait tablets and large phones, 600px and up) */
@media only screen and (max-width: 600px) {

    /*  Define CSS rules for mobile device here */

    .col-2,
    .col-3{
        width: 100% !important;
    }

}



/*  CSS rules for rest of the screen size  */
.col{
    min-height: 10vh;
    float: left;
    text-align: center;
}

.col-1{
    width: 100%;
    background: lime;
}

.col-2{
    width: 50%;
    background: pink;
}

.col-3{
    width: 33.3%;
    background: cyan;
}

始终为移动设备设计First.Mobile首先意味着在为桌面或任何其他设备设计之前为移动设备设计(这将使页面在较小的设备上显示速度更快)。

您可以在 Media Query 移动设备中为移动设备定义 CSS 规则。 然后为移动设备 Media Query 块之外的相同元素修改 属性 以使其在其他屏幕上看起来不错。

您还可以为多个屏幕定义 CSS 媒体查询。例如如下:

 /* Extra small devices (phones, 600px and down) */
@media only screen and (max-width: 600px) {...}

/* Small devices (portrait tablets and large phones, 600px and up) */
@media only screen and (min-width: 600px) {...}

/* Medium devices (landscape tablets, 768px and up) */
@media only screen and (min-width: 768px) {...}

/* Large devices (laptops/desktops, 992px and up) */
@media only screen and (min-width: 992px) {...}

/* Extra large devices (large laptops and desktops, 1200px and up) */
@media only screen and (min-width: 1200px) {...} 

您可以调整它并根据您的需要进行调整。实验。
