Answer 1

There are a couple things going on:
First, I changed your CSS to have mobile/small screens first. This way you can have all your styles for the buttons and then just change the positioning for larger screens. Second, you can easily combine styles for your buttons so you don't have a bunch of repeating styles.
Hopefully this is what you're looking for:
* {
box-sizing: border-box;
}
.bottoni,
.bottoni2 {
position: relative;
}
.bottoni > a,
.bottoni2 > a {
display: block;
width: 100%;
padding: 10px 40px;
margin: 20px 0;
background: rgba(0, 0, 0, 0.9);
border-left: 15px solid #f45341;
border-right: 3px solid #f45341;
text-decoration: none;
color: #fff;
text-transform: uppercase;
font-size: 30px;
background: linear-gradient(to left, #f45341 50%, rgba(96, 96, 96, 0.4) 50%);
background-position: 0% 0%;
background-size: 200%;
transition: background .3s ease-in-out, color .3s ease-in-out;
font-family: pricedown;
border-radius: 5px;
text-align: left;
}
.bottoni > a:hover,
.bottoni2 > a:hover {
color: #fff;
background-position: -100% 0%;
cursor: pointer;
}
#media screen and (min-width: 768px) {
.bottoni,
.bottoni2 {
position: absolute;
width: 300px;
top: 50%;
right: 0;
transform: translatey(-100%);
}
.bottoni > a,
.bottoni2 > a {
position: relative;
width: 300px;
}
.bottoni2 {
left: 0;
right: auto;
}
.bottoni2 > a {
border-right: 15px solid #f45341;
border-left: 3px solid #f45341;
}
.bottoni2 > a:hover {
border-right: 15px solid #f45341;
}
}
<div class="bottoni">
<a target="blank_" id="store" href="http://store.sparocraft.eu">Store</a>
<a target="blank_" id="votaci" href="http://vota.sparocraft.eu">Votaci</a>
</div>
<div class="bottoni2">
<a target="blank_" id="ts" class="offline" href="ts3server://ts.sparocraft.eu">TeamSpeak</a>
