Solution 1 :

Just change the attribute of overflow in Text class of your CSS to hidden:

.Text {
    width: 500px;
    min-height: 500px;
    height: auto;
    overflow: hidden;
    margin: 50px 30px;
    border: 2px solid red;
}

Basically, since your overflow was set to auto, it tried to scale the content for which it had to show the scrollbar. For more details check out this W3schools documentation : https://www.w3schools.com/css/css_overflow.asp

Solution 2 :

You can disable scrollbars with overflow: hidden; It can be overflow in general, but if you want only horizontal to be hidden, you can put overflow-x: hidden, and for vertical: overflow-y: hidden
So, in your css you can put it like this:

.Resume {
    overflow-x: hidden;
    width: 180px;
    height: 60px;
    margin: 0px auto;
    border-radius: 5px;
    background-color: #00d363;
    border: 1px solid #00d363;
    font-family: "IranSans";
    text-align: center;
}

Solution 3 :

or you can do

.Text > div {
    box-sizing: border-box;
}

so all nested divs with border fits into the parent el
