does anyone know the css how to fix this issue

thank you

Assuming the wrapping <div> element has the id myDiv:

#myDiv {
  height: 300px;
  overflow: auto;
}

Off the top of my head, I'd wrap a div around your images, and set the height in the style element of that div to 300px. Then set the overflow (also in the style element) to scroll

<div style="height: 300px; overflow: auto">
... your images
</div>
