Every time you click 'Roll!', a gif pops up, lingers for a moment, and then vanishes. The functionality is on point, except for the fact that when the gif appears, it causes everything below it to shift, and when it disappears, everything goes back to its original position. Is there a way to make this gif appear and disappear without causing such movement? And all without resorting to absolute positioning?
To eliminate this behavior, one can utilize absolute positioning to detach the element from the standard flow of elements. This method is considered the ideal solution for handling such situations effectively.
What are the drawbacks of not implementing position:absolute? It may seem like a logical choice to have something displayed on top of your regular content.
One alternative solution is to utilize negative margin. For instance, if your image is 40px tall, you could apply a margin-bottom of -40px. However, I would caution against this approach in favor of using position:absolute.
UPDATE: Oops, looks like someone else already made that suggestion.
Absolutely, absolute positioning is the way to go. This code snippet will take you closer to your goal:
<img id="loader" style="position: absolute; display: none; left: 50%; margin-left: -110px;" src="img/ajax-loader.gif">
I highly suggest steering clear of inline CSS and JavaScript, as well as HTML elements like <center> (CSS should handle that). To style this specific element, you would use the following CSS rule:
#loader {
display: none;
position: absolute;
left: 50%;
margin-left: -110px;
}
To improve the layout, eliminate the <br> tags and contain the gif in a fixed height container:
<button>Roll!</button>
<div style="height:20px"><img id="loader" src="img/ajax-loader.gif" /></div>
You can customize the margins using additional CSS for a more personalized look.
To create a unique effect, apply a negative bottom margin to the gif that matches its height. For example, if the gif is 30px tall, you can use the following CSS:
#myGif {
margin-bottom: -30px;
}
Thank you for offering your assistance, but I was able to discover my own solution that I believe works even more effectively than my initial idea. If you're interested, you can revisit the page to see it in action. However, I'll explain what I did here. Essentially, I simply included...
<style type="text/css">
.load {
background-image: url('img/ajax-loader2.gif');
background-repeat: no-repeat;
background-position: bottom right;
}
#printout {
border: 1px black dotted;
font-size: 12pt;
text-align: left;
padding: 10px;
height: 100px;
width: 400px;
}
</style>
After that, I proceeded with...
$("button").click(function () {
var v = $("select").attr("value");
--> $("#printout").addClass("load"); <--
$.get("randloot.php", { "table" : v }, function(data) {
--> $("#printout").removeClass(); <--
if(data.roll != 0) {
$('#printout').text("Roll - " + data.roll +
"\nArmor - " + data.armor +
"\nPrice - " + data.price + "gp");
}
else
$('#printout').text("Oops");
}, "json");
});
In my opinion, the final outcome is refined and inconspicuous. It may consist of a few additional lines compared to other mentioned solutions, but this approach can be adapted to numerous scenarios with minimal modifications.
