What is the most effective method for enlarging elements using Javascript?

I have come across many different methods for expanding elements on webpages, such as using divs with javascript and jquery. I am curious to know what the most optimal and user-friendly approach is in terms of performance, among other things.

For instance, I am currently working on a new website where I have a news section on the homepage. I want the news items to have a specific height, like 250px, and to span the width of the container (using the 960 grid CSS).

Here is my layout:

<div class="grid_10 news">
   <article></article>
   <article></article>
   <article></article>
   <article></article>
</div>

Each article includes information, metadata, and a "read more" link on the right side that should expand the article to its full height.

Currently, I have not specified a height or applied any specific CSS to the article (other than display: block). What technique would you suggest for achieving this, and how would you go about implementing it?

Cheers.

Answer №1

If you're uncertain about the upcoming height, consider setting it to auto. For instance, if the article contains a "read more" button or link, you can dynamically adjust the height using jQuery:

$(".your_read_more_button").parent().css('height', 'auto');

While this method lacks direct animation, you can achieve smooth transitions by either cloning the element to measure the displayed height, or using slideUp() and slideDown() with intermediate height changes.

When you know the before and after heights, utilize CSS3 transitions:

.news article
{
   -moz-transition: height 1s ease-in-out;
   -webkit-transition: height 1s ease-in-out;
   -o-transition: height 1s ease-in-out;
   transition: height 1s ease-in-out;
}

.expanded
{
   height: 250px;
}

Alternatively, employ jQuery animate for specific height changes:

$('article').stop(true,true).animate({height: 250px}, 400);

This method smoothly transitions between two heights without the visibility glitch often seen with .toggle().
