如何设置占位符文本的颜色和字体样式

2018-06-25 04:21:06

我想将颜色设置为占位符，将字体样式更改为粗体，然后增加大小。

我怎样才能做到这一点？我是否应该为占位符赋予风格，还是有其他方法可以实现这一目标？我想在下面的结果中设置颜色和更改字体样式，以在所有浏览器中选择大小。

<!doctype html>



<style>html { font-size: 14px; font-family: Arial, Helvetica, sans-serif; }


.k-dropdown-wrap{
  border-width: 5px !important;
  border-color: #D8D3D3 !important;
}

}



</style>

<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.2.607/styles/kendo.common-material.min.css" />
<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.2.607/styles/kendo.material.min.css" />
<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.2.607/styles/kendo.default.mobile.min.css" />

<script src="//kendo.cdn.telerik.com/2016.2.607/js/jquery.min.js"></script>
<script src="//kendo.cdn.telerik.com/2016.2.607/js/kendo.all.min.js"></script>



    <div id="example" role="application">
        <div id="tshirt-view" class="demo-section k-content">

        
        <select id="size" placeholder="Select City..." style="width: 300px;" >
          <option />
          <option />Newyork
          <option />Hyderabad
          <option />Bangalore
          <option />Kolkata
          <option />Delhi
        </select>


    </div>

        <script>
            $(document).ready(function() {
                // create ComboBox from input HTML element

                // create ComboBox from select HTML element
                $("#size").kendoComboBox();


                var select = $("#size").data("kendoComboBox");



            });


        </script>
    </div></!doctype>

您可以使用以下代码进行跨浏览器支持 ：

对于Google Chrome ：

.element::-webkit-input-placeholder {
    color: blue;
    font-weight: bold;
}

对于Mozilla Firefox ：

.element::-moz-placeholder {
    color: blue;
    font-weight: bold;
}

对于Internet Explorer ：

.element:-ms-input-placeholder {
    color: blue;
    font-weight: bold;
}

对于Opera ：

.element:-o-input-placeholder {
    color: blue;
    font-weight: bold;
}

   color: red;  
   font-weight: 800;
}

:-ms-input-placeholder {  
   color: red;  
   font-weight: 800;
}

<!doctype html>



<style>html { font-size: 14px; font-family: Arial, Helvetica, sans-serif; }


.k-dropdown-wrap{
  border-width: 5px !important;
  border-color: #D8D3D3 !important;
}
::-webkit-input-placeholder {
   color: red;
}
}



</style>

<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.2.607/styles/kendo.common-material.min.css" />
<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.2.607/styles/kendo.material.min.css" />
<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.2.607/styles/kendo.default.mobile.min.css" />

<script src="//kendo.cdn.telerik.com/2016.2.607/js/jquery.min.js"></script>
<script src="//kendo.cdn.telerik.com/2016.2.607/js/kendo.all.min.js"></script>



    <div id="example" role="application">
        <div id="tshirt-view" class="demo-section k-content">

        <h4 style="margin-bottom: .5em;">Select City</h4>
        <select id="size" placeholder="Select City..." style="width: 300px;" >
          <option />
          <option />Newyork
          <option />Hyderabad
          <option />Bangalore
          <option />Kolkata
          <option />Delhi
        </select>


    </div>

        <script>
            $(document).ready(function() {
                // create ComboBox from input HTML element

                // create ComboBox from select HTML element
                $("#size").kendoComboBox();


                var select = $("#size").data("kendoComboBox");



            });


        </script>
    </div></!doctype>

你可以使用占位符伪元素和font-weight使它更大胆

<!doctype html>



<style>html { font-size: 14px; font-family: Arial, Helvetica, sans-serif; }


.k-dropdown-wrap{
  border-width: 5px !important;
  border-color: #D8D3D3 !important;
}
    ::-webkit-input-placeholder {
        font-weight: 800; 
        font-size: 16px;
    }
    :-moz-placeholder {
        font-weight: 800; 
        font-size: 16px;
    }
    ::-moz-placeholder {
        font-weight: 800; 
        font-size: 16px;
    }
    :-ms-input-placeholder {
        font-weight: 800; 
        font-size: 16px;
    }
}



</style>

<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.2.607/styles/kendo.common-material.min.css" />
<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.2.607/styles/kendo.material.min.css" />
<link rel="stylesheet" href="//kendo.cdn.telerik.com/2016.2.607/styles/kendo.default.mobile.min.css" />

<script src="//kendo.cdn.telerik.com/2016.2.607/js/jquery.min.js"></script>
<script src="//kendo.cdn.telerik.com/2016.2.607/js/kendo.all.min.js"></script>



    <div id="example" role="application">
        <div id="tshirt-view" class="demo-section k-content">

        <h4 style="margin-bottom: .5em;">Select City</h4>
        <select id="size" placeholder="Select City..." style="width: 300px;" >
          <option />
          <option />Newyork
          <option />Hyderabad
          <option />Bangalore
          <option />Kolkata
          <option />Delhi
        </select>


    </div>

        <script>
            $(document).ready(function() {
                // create ComboBox from input HTML element

                // create ComboBox from select HTML element
                $("#size").kendoComboBox();


                var select = $("#size").data("kendoComboBox");



            });


        </script>
    </div></!doctype>
