I couldn't figure out How to set time on jQuery .css property I found one answer which is the closest to my question in jQuery change CSS after a certain amount of time

Here is my code:

            $("#title").css("font-size", "100%");  
            setTimeout(function(){ $("#title").css("font-size", "100%"); },2000)

I don't know what is wrong with that. It seems like the solution I mentioned above doesn't work for me. Thank you in advance guys


Thanks for the response folks, there are several things that I want to re-explain:

  1. I initially set the font-size to 150% in my CSS, which mean through my jQuery, I expected it to change the font-size into 100%.
  2. I think I've misinterpreted the code, what I wanted to set is the time for decreasing gradually and not the timer

Basically, I want to change the font-size using jquery with transition, and not a sudden change

The trouble is you first set font-size: 100% immediately, then you set it to the same value again after 2 seconds. Ie, you aren't changing the css.

To set the css value when clicked, and then set it to something else 2 seconds later, use different values in each call to .css(). Eg, to decrease the font size by half initially, then bring it back to normal size 2 seconds later:

        $("#title").css("font-size", "50%");
        setTimeout(function(){ $("#title").css("font-size", "100%"); },2000);

Edit: To gradually decrease the font size, you want to use .animate():

        $("#title").animate({ "font-size": "50%" }, 2000);


how to add a CSS attribute just for specific time via JQuery (revert , css({"border": "1px solid #ccc"}); });. But the above code will be applied for ever, how can I limit it for a specific period ? share. I have a navigation that, when one of it's nav items is clicked, will use jQuery to change it's z-index to 0. Then, after 2 seconds, I would like the z-index to be changed to 2. I tried using delay() but apparently that doesn't work when changing the CSS.

Change the font-size after the 2 second timeout. For example:

  $("#title").css("font-size", "100%");  
  setTimeout(function(){ $("#title").css("font-size", "80%"); },2000)                               

I tried it in the following jsfiddle and it worked fine for me.
