Modify CSS with JavaScript





In certain cases, where a browser does not support standard-compliant CSS, you may need to resort to using JavaScript to achieve a certain stylistic effect.


The following code provides the syntax necessary to use JavaScript to modify styles:


document.getElementById(id_of_element).style.javascript_property = "style";

If only it were that simple! How JavaScript refers to style properties varies a little bit from CSS.  The following table will assist you in finding the correct JavaScript style.

Using the table below, here's a JavaScript example on how to modify the border width property of an element:

<p id="example">This is an example.</p>

<script>
  document.getElementById('example').style.borderWidth = '4px';
</script>
