# # 自定义主题色

Foxit PDF SDK for Web 提供了一个公共方法 `setThemeColor`，允许用户自定义主题色。具体如下：

    PDFViewCtrl.shared.setThemeColor([
            {
                dom: document.body, // Applied globally.
                colors: {
                    primary: "#409eff", // Optional. Sets the color for UI components like buttons and dropdowns.
                    background: "#999999", // Optional. Sets the background color for pages and input fields.
                    border: "", // Optional. Sets the border color. An empty string means using the default value.
                    link: "#9E3ABF", // Optional. Sets the color of links.
                    text: "#006ddd", // Optional. Sets the color of the text.
                },
            },
            {
                dom: document.getElementsByClassName("fv__ui-tab-nav")[0], // Applied to a specific DOM element.
                colors: {
                    text: "#d96f3f"
                },
            },
        ]);
