javascript-对角放置HTML元素

我是Java语言&的新手.对HTML而言相对较新.我想知道应该使用哪种语言(纯html或Javascript&html).一种算法的一些建议,以便执行以下操作：

在背景上放置4个正方形,但将它们对角放置.每个正方形都是一个链接,您可以单击以转到不同的页面.那么,如何才能像下面的图片一样对角放置html元素？

我相信我的代码看起来像这样：

<script>
    function positionIt()
    {
        var screenW = // javascript function to get screen width??;
        var screenH = // javascript function to get screen height??;

        var sq1 = document.getElementById( "square1" );
        var sq2 = document.getElementById( "square2" );
        var sq3 = document.getElementById( "square3" );
        var sq4 = document.getElementById( "square4" );

        // What javascript functions set a elements x,y positions?
        // Should I use another way of positioning the square (not by absolute terms)
        sq1.setXPos( screenW / 4 );
        sq1.setYPos( screenH / 4 );

        sq2.setXPos( screenW / 3 );
        sq2.setYPos( screenH / 3 );
    }
</script>

// OR if I use css
.menu { background-color: blue; }
/* Position the square in absolute terms diagonally */
#square1 { x=200; y=200; }
#square2 { x=300; y=300; }
#square3 { x=400; y=400; }
#square4 { x=500; y=500; }

<div class="menu" onl oad="positionIt()">
    <a id="square1" href="home.html"><img src="square.jpg" /></a>
    <a id="square2" href="home.html"><img src="square.jpg" /></a>
    <a id="square3" href="home.html"><img src="square.jpg" /></a>
    <a id="square4" href="home.html"><img src="square.jpg" /></a>
</div>

我试图保持您要求的数字.

HTML：

<div class="menu">
    <a id="square1" href="home.html"><img src="http://dummyimage.com/100/f90/fff" /></a>
    <a id="square2" href="home.html"><img src="http://dummyimage.com/100/f90/fff" /></a>
    <a id="square3" href="home.html"><img src="http://dummyimage.com/100/f90/fff" /></a>
    <a id="square4" href="home.html"><img src="http://dummyimage.com/100/f90/fff" /></a>
</div>

CSS：

.menu {
    background: blue;
    width: 800px;
    height: 800px;
    position: relative
}
/* Position the square in absolute terms diagonally */
#square1 { position:absolute; left:200px; top:200px; }
#square2 { position:absolute; left:300px; top:300px; }
#square3 { position:absolute; left:400px; top:400px; }
#square4 { position:absolute; left:500px; top:500px; }
