Web users are lazy 🙂 Everything must go fast, and the less clicks and the less scrolling they have to do, the better!
This is why I think that « burger » menu on mobile is not a good feature: user have to click to see the menu and where they could go on the website.
Of course, when there are a too large number of menu items, you may have no other choice. But when it is possible, I think that menu at mobile screen bottom is a good feature, because mobile users are used to buttons a the bottom of their mobile.
But a bottom menu for desktop may not be a good idea.
Here is the CSS snippet I am using on this website to have « something » at the screen bottom on mobile and at the screen top on desktop. Of course, you can tune things as paddings.
add_action( 'wp_head', function () { ?>
<style>
.my_footer {
position: fixed;
width:100%;
left:0;
right:0;
overflow: hidden;
background-color: #000000;
z-index:2;
}
.box {
display: flex;
align-items: flex-start;
justify-content: space-around;
}
.box :first-child {
align-self: center;
}
@media (max-width:767px){
.box {
padding-top: 5px;
padding-bottom: 5px;
padding-right: 5px;
padding-left: 10px;
}
.my_footer {
bottom: 0;
}
}
@media (min-width:768px){
.box {
padding-top: 15px;
padding-bottom: 15px;
}
.my_footer {
top: 0;
}
}
</style>
<?php } );
And here is the snippet for the « something » you want to put at bottom/mobile and top/desktop.
<div class="my_footer">
<div class="box">
Your something goes here
</div>
</div>
Here are some other websites I have designed that use bottom/top menus:
You can get the mobile layout on a desktop by narrowing your window, and get the desktop layout on a mobile by turning your mobile horizontally.
