Block image in Highlighted Region won't resize

Hi,

I have a block with an image inserted within the Highlighted Region.

I have tried targeting the block id and the image with CSS, but I cannot get its width to enlarge.

I have even targeted the image source of my block as follows and it still won’t enlarge:

<img alt="Picture of a clock with birds circling" data-align="center" data-entity-type="file" data-entity-uuid="615020cc-a11e-4fb0-ab00-3e48e741029c" src="/sites/default/files/inline-images/clock-474128_1280.jpg" width="960" />
<p>&nbsp;</p>

Any suggestions would be appreciated.

Stephen
