When comparing two images, both 512px in height and width, the plus symbol appears larger 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;
}
