I've developed a web page where there are several struts tags. On page load, only one tag is shown while all other tags are hidden. This is by the `onLoad()` in the body tag that calls a Javascript function(`.style.display = 'none';`) to hide the tags initially. 

But when the network speed is slow, when the page loads, there is a brief flicker between the tags being shown first and then hidden by the `onLoad()`'s Javascript call.

Is there an alternate to hide tags on load without seeing this flicker?
