基本上我有两种不同的风格，我想在移动设备上制定。一组用于纵向视图，另一组用于横向。我在测试过程中遇到了一个问题，因为我的 Galaxy S4 在纵向视图中显示应该是我的横向视图，因为它的分辨率很大。我的初始 CSS 编写如下。

#checkoutoptions {
    border: 2px solid #c6c6c6;
    border-radius: 10px;
    padding: 10px;
    position: relative;
}

#checkoutoptions h3 {
    font-size: 1.2em;
    font-weight: 500;
    margin-left: 35px;
    margin-top: 10px;
}

#checkoutoptions h4 {
    color: #000;
    font-size: 1.2em;
    font-weight: 600;
    margin-bottom: 0;
}

#checkoutoptions p {
    font-size: .8em;
    margin-bottom: 5px;
}

#checkoutoptions .label {
    display: inline-block;
    font-size: .9em;
    margin: 10px 0 20px;
}

#checkoutoptions .input {
    border: 1px solid #eee;
    border-radius: 5px;
    box-shadow: 0 0 0 4px #f4f4f4;
    font-size: 1em;
    height: 2.25em;
    margin-top: 10px;
}

#checkoutoptions .number {
    background-color: #c6c6c6;
    border-radius: 15px;
    color: #fff;
    height: 30px;
    line-height: 30px;
    position: absolute;
    text-align: center;
    top: 15px;
    width: 30px;
}

#checkoutoptions .dividingLine {
    border-bottom: 1px solid #c6c6c6;
    padding-bottom: 10px; 
}

#checkoutoptions #signin {
    border-bottom: 1px solid #c6c6c6;
    padding-bottom: 10px; 
}

#checkoutoptions .forgotpassword {
    font-size: .75em;
    margin-top: 15px;
}

@media only screen and (min-width: 321px){
    #checkoutoptions {
        overflow: auto;
    }

    #signin {
        float: left;
        clear: both;
        width: 45%;
    }

    .registeroptions { 
        float: left;
        position: relative;
        width: 50%;
    }

    #checkoutoptions #signin {
        border-bottom: 0;
        padding-bottom: 0; 
        border-right: 1px solid #c6c6c6;
        margin-right: 10px;
    }
}

通过一些研究，我发现有可用于 HD/Retina 屏幕的媒体查询。所以我添加了以下内容：

@media
only screen and (-webkit-min-device-pixel-ratio: 1.25),
only screen and ( min--moz-device-pixel-ratio: 1.25),
only screen and ( -o-min-device-pixel-ratio: 1.25/1),
only screen and ( min-device-pixel-ratio: 1.25),
only screen and ( min-resolution: 200dpi),
only screen and ( min-resolution: 1.25dppx)
{
    #checkoutoptions {
        overflow: auto;
    }

    #signin {
        float: none;
        clear: both;
        width: 100%;
    }

    .registeroptions { 
        float: none;
        position: relative;
        width: 100%;
    }

    #checkoutoptions #signin {
        border-right: 0;
        margin-right: 0; 
        border-bottom: 1px solid #c6c6c6;
        padding-bottom: 10px;
    }
}

这非常适合让我的高清屏幕完全按照我的意愿显示纵向视图。下一个，景观视图！这当然是我遇到了死胡同的地方。我还没有想出一个对我有用的查询，到目前为止，研究还没有对此进行任何讨论。关于如何为 Landscape HD/Retina 设备编写正确的媒体查询有什么想法吗？

到目前为止我尝试过的事情：

@media
only screen and (min-width; 1081px) and (-webkit-min-device-pixel-ratio: 1.25),
only screen and (min-width; 1081px) and ( min--moz-device-pixel-ratio: 1.25),
only screen and (min-width; 1081px) and ( -o-min-device-pixel-ratio: 1.25/1),
only screen and (min-width; 1081px) and ( min-device-pixel-ratio: 1.25),
only screen and (min-width; 1081px) and ( min-resolution: 200dpi),
only screen and (min-width; 1081px) and ( min-resolution: 1.25dppx)
{
    #checkoutoptions {
        overflow: auto;
    }

    #signin {
        float: left;
        clear: both;
        width: 45%;
    }

    .registeroptions { 
        float: left;
        position: relative;
        width: 50%;
    }

    #checkoutoptions #signin {
        border-bottom: 0;
        padding-bottom: 0; 
        border-right: 1px solid #c6c6c6;
        margin-right: 10px;
    }
}

目前它正在工作（可以使用更多测试）：

/* Portrait View */
@media
only screen and (max-width: 360px) and (-webkit-min-device-pixel-ratio: 1.25),
only screen and (max-width: 360px) and ( min--moz-device-pixel-ratio: 1.25),
only screen and (max-width: 360px) and ( -o-min-device-pixel-ratio: 1.25/1),
only screen and (max-width: 360px) and ( min-device-pixel-ratio: 1.25),
only screen and (max-width: 360px) and ( min-resolution: 200dpi),
only screen and (max-width: 360px) and ( min-resolution: 1.25dppx)
{
    /* Styles */
}

/* Landscape View */
@media
only screen and (min-width: 361px) and (-webkit-min-device-pixel-ratio: 1.25),
only screen and (min-width: 361px) and ( min--moz-device-pixel-ratio: 1.25),
only screen and (min-width: 361px) and ( -o-min-device-pixel-ratio: 1.25/1),
only screen and (min-width: 361px) and ( min-device-pixel-ratio: 1.25),
only screen and (min-width: 361px) and ( min-resolution: 200dpi),
only screen and (min-width: 361px) and ( min-resolution: 1.25dppx)
{
    /* Styles */
}

您可以orientation:landscape在媒体查询中使用，而不是min-width：

@media
only screen and (orientation:landscape) and (-webkit-min-device-pixel-ratio: 1.25),
only screen and (orientation:landscape) and ( min--moz-device-pixel-ratio: 1.25),
only screen and (orientation:landscape) and ( -o-min-device-pixel-ratio: 1.25/1),
only screen and (orientation:landscape) and ( min-device-pixel-ratio: 1.25),
only screen and (orientation:landscape) and ( min-resolution: 200dpi),
only screen and (orientation:landscape) and ( min-resolution: 1.25dppx)
