Appending HTML style in JS works on PC but not on Android

Hi. I am adding the following style via Javascript to individual html elements. (In my case when an image has no content I want to set the display to 'none' so the 'not loaded' graphic cant be seen and the layout is arranged accordingly)

myImageElement.style.display = 'none';

<img class="image" src="" style="display: none;">

<img class="image" src="">

The WAAAY better way to do this is using CSS (logic) alone:

/* if no image source set display to none!! */
.image[src=''] {
display:none;;
visibility:hidden;
 /* elseif */
}
