I have tried to place my buttons in the middle, but I have no idea what to do, as I'm not the best at CSS.
I don't know, if I'm doing it right in my code, but I have tried to place it in the center.
What should I do to place my buttons in the Middle of the screen?
<style>
    body {
    background-image: url(http://1-background.com/images/silk/grey-silk-website-background.jpg);
    }
    .button {
        display:block;
        text-align:center;
    }
    h1{
         text-align: center;
    }
    .remove{
        color: red;
        align-items: center;
    }
    .create{
        color: green;
        align-items: center;
    }
    .test{
        color: blue;
        align-items: center;
    }
</style>
<body>
    <form>
        <h1>
            <select id="mySelect" style="width:400px" size="10"  multiple>
                <option id=" hello">hello</option>
            </select>
            <br />
            <input type="text" name="name" value="text " style="width:350px" />
        </h1> 
    </form>
    <br>
