I use this code

Initialize new codemirror element in HTML/JS:

<body>
<div id="code"></div>

<script>
    var editor = CodeMirror(document.getElementById('code'), {
        lineNumbers: true,
        lineWrapping: false,
        matchBrackets: true,
        closeBrackets: true,
        autoCloseBrackets: true,
        styleActiveLine: true,
        mode: "text/x-csrc",
    });
</script>
</body>

Set height for codemirror in CSS:

.CodeMirror {
    font-size: 1em;
    float: left;
    width: 100%; 
    height: 100%;
}
.cm-wrap { height: 100% }
.cm-scroller { overflow: auto }

But codemirror only fills 50% of the height. Why and how to fix this?

It looks like you missed some styles for the page. If you use the following CSS, CodeMirror will take 100% height and width.

    html {
        height: 100%;
        width: 100%;
        min-width: 100%;
        min-height: 100%;
    }

    body {
        height: 100%;
        width: 100%;
    }

    #code {
        height: 100%;
        width: 100%;
    }

    .CodeMirror {
        font-size: 1em;
        float: left;
        width: 100%;
        height: 100%;
    }

    .cm-wrap {
        height: 100%
    }

    .cm-scroller {
        overflow: auto
    }
