}

you can add inline styles index.html file:

<style>     body {         background-color: green;     }      h1 {         color: red;         margin-left: 40px;     }     ... </style> 

or can create styles.css, include them:

<link rel="stylesheet" href="styles.css"> 

and use webview#loaddatawithbaseurl:

webview.loaddatawithbaseurl("file:///android_res/raw/", loaddata(readtextfromresource(r.raw.index), "text/html", "utf-8", "");
