I cannot set a dynamic width and height with CSS

[COD3BREAK3R]

I would like to know how to remove the width and height that the library includes by default so that I can give it my own width and height using CSS styles

Hi, i used this method:

< img id="js-qr-code" src="" alt="qr-code" >

<script> const opts = { errorCorrectionLevel: 'H', type: 'image/jpeg', quality: 0.3, margin: 0.4, color: { dark: '#5061CE', light: '#FFFFFF' } } QRCode.toDataURL('test content', opts, function (err, url) { if (err) throw err document.querySelector('#js-qr-code').src = url }) </script>
