# usage

```javascript
<AutoHeightWebView
    onHeightUpdated={height => console.log(height)},
    /*
    if set to false may cause some layout issues (width of container will be than width of screen) on android
    if set to true may cause some layout issues (smaller font size) on ios
    */
    scalesPageToFit={Platform.OS === 'android' ? true : false}
    // baseUrl not work in android 4.3 or below version
    enableBaseUrl={true}
    // offset of rn webview margin 
    heightOffset={5}
    // default width is the width of screen
    style={customStyle}
    // enable animation by default
    enableAnimation={true},
    // only works on enable animation
    animationDuration={255},
    // or uri
    source={{ html: `<p style="font-weight: 400;font-style: normal;font-size: 21px;line-height: 1.58;letter-spacing: -.003em;">Tags are great for describing the essence of your story in a single word or phrase, but stories are rarely about a single thing. <span style="background-color: transparent !important;background-image: linear-gradient(to bottom, rgba(146, 249, 190, 1), rgba(146, 249, 190, 1));">If I pen a story about moving across the country to start a new job in a car with my husband, two cats, a dog, and a tarantula, I wouldn’t only tag the piece with “moving”. I’d also use the tags “pets”, “marriage”, “career change”, and “travel tips”.</span></p>` }}
