background-color: none;
border-radius:1px;
border-radius:1px;
border-radius: 66px;
border: 1px solid #ffffff;
display:inline-block;
color:#ffffff;
padding:1px 22px;
}
.myButton:hover {
background-color:#ff00ff;

编辑（来回评论后）：
要使文本居中并让悬停效果覆盖按钮的整个内部，同时保持按钮的宽度不变，请按如下所示更改css：
当前：
#menu-main li:last-child a {
padding: 7px 19px 5px 15px;
box-sizing: border-box;
padding-border: 42px;
}
#menu-main li:last-child {
box-shadow: inset 0px 0px 0px 0px #none;
box-shadow: inset 0px 0px 0px 0px #none;
box-shadow: inset 0px 0px 0px 0px #none;
background-color: none;
border-radius: 8px;
border-radius: 8px;
border-radius: 66px;
border: 1px solid #ffffff;
display: flex;
color: #ffffff;
padding: 0px 20px;
text-align: center justify-content:center;
align-items: center;
height: 40px;
line-height: 0px;
width: 200px;
box-sizing: border-box;
}
更改为（删除按钮和文本上的填充，在文本上放置边框半径，将文本的宽度和高度设置为与按钮相同，并且我还删除了没有做任何事情/写错了的东西）
新功能：（将width: 100%添加到导航栏，并向float: right的媒体查询添加768px或以上的屏幕上的按钮）：
#menu-main {
width: 100%;
}
#menu-main li:last-child a {
padding: 0px;
line-height: 40px;
border-radius: 66px;
height: 100%;
width: 100%;
}
#menu-main li:last-child {
border-radius: 66px;
border: 1px solid #ffffff;
text-align: center;
height: 40px;
width: 175px;
margin-left: 20px;
margin-top: 5px;
margin-bottom: 5px;
}
@media only screen and (min-width: 768px) {
#menu-main li:last-child {
float: right;
}
}

很高兴提供帮助！
我相信您要更改此部分的填充值吗？：
#menu-main li:last-child{
box-shadow:inset 0px 0px 0px 0px #none;
box-shadow:inset 0px 0px 0px 0px #none;
box-shadow:inset 0px 0px 0px 0px #none;
background-color: none;
border-radius:1px;
border-radius:1px;
border-radius: 66px;
border: 1px solid #ffffff;
display:inline-block;
color:#ffffff;
//padding:1px 22px;
padding:1px 10px;
}
您可能想弄弄第二个像素值，直到获得所需的值，但可能是10px。.padding:1px 10px;
设置padding时，第一个值是上/下，第二个值是左/右。因此，调整第二个值将改变文本两侧的填充量。
希望这会有所帮助，如果您有任何疑问，请告诉我！

您出了什么问题，无需两次编写规则：
#menu-main li:last-child{
box-shadow:inset 0px 0px 0px 0px #none;
box-shadow:inset 0px 0px 0px 0px #none;
box-shadow:inset 0px 0px 0px 0px #none;
background-color: none;
border-radius:1px;
border-radius:1px;
border-radius: 66px;
border: 1px solid #ffffff;
display:inline-block;
color:#ffffff;
padding:1px 22px;
}
您可以使用：
button{
text-align:center
}
或使用将display flex添加到包装元素的居中子元素：
div{
display:flex;
justify-content:center;
align-items:center;
}
