How do you style the <paper-input> tag in Polymer 1.0

您能显示如何专门自定义样式的标签文本颜色，下划线颜色，输入文本颜色以及如何使用custom-style进行访问吗?

Can you show how to specifically custom style the label text color, the underline color, input text color, and how to access them using custom-style?

推荐答案

您可以通过更改

You can change the appearance of <paper-input> by changing the custom properties listed over here (The information has been moved for the most recent version - it is available for versions older than v1.1.21).

这是一个例子:

<style is="custom-style">
:root {
        /* Label and underline color when the input is not focused */
        --paper-input-container-color: red;

        /* Label and underline color when the input is focused */
        --paper-input-container-focus-color: blue;

        /* Label and underline color when the input is invalid */
        --paper-input-container-invalid-color: green;

        /* Input foreground color */
        --paper-input-container-input-color: black;
}
</style>

:root选择器用于定义自定义适用于所有自定义元素的属性.您还可以定位特定元素而不是:root:

The :root selector is used to define custom properties that apply to all custom elements. You can also target a specific element instead of :root:

<style is="custom-style">
    paper-input-container.my-class {
        --paper-input-container-color: red;
        --paper-input-container-focus-color: blue;
        --paper-input-container-invalid-color: green;
        --paper-input-container-input-color: black;
    }
</style>
