I have been trying to make an image 100% width. The content builder UI sets the < picture > tag at width:100% and not the < img > tag. As a result there is an overflow. Is it possible to set < img > to 100%?
Left image is how the editor looks.
Right image is how I would like it to look (I edited through Chrome debugger)
Another solution is adding custom CSS (e.g..some-custom-class img { width: 100% }). You can add a custom class by navigating to the styles tab and scrolling down to the advanced section. Then you can add custom CSS in the “CSS/JS” section at the bottom of the data tab
