Question

I would like to know the height of a paragraph. Is there any solution? Thanks.

Answer 1

Not in PHP, no. The paragraph will be rendered in the browser; a number of variables can influence the actual height: Operating System font size settings, Zoom settings, availability of fonts…. therefore, the height can be determined only in client-side JavaScript after the page has been rendered.

The jQuery framework has the convenient .height() that will give you the computed height of a HTML element and bridges a number of cross-browser issues one would have to take care of manually:

<p id="paragraph>Lorem Ipsum Dolor amet....</p>

$(document).ready(function() {
 alert("Height is "+ $("#paragraph").height() + "Pixels");    
} );
