I have two pictures that have 512px in height and 512px in width. Whatsoever the plus symbol is bigger than the shutdown button.
HTML:
<div class="logout">
<a href="someLink">
<img name="logout" alt="logout" src="red_shutdown.png">
</a>
</div>
<div class="plus-symbol">
<img name="plus" alt="create-post" src="plus-symbol.png">
</div>
CSS:
div.logout {
position: fixed;
bottom: 10%;
right: 1.32%;
border: 0;
}
div.plus-symbol {
position: fixed;
bottom: 10%;
right: 1.32%;
border: 0;
}
You can just make the parent tag of 512*512. then just make the image to be
width:100%; height:100%;
Also check from inspect if the images are overflowing or not if yes then overflow:hidden
