Tips for utilizing .animate() to increase width from a particular direction

Currently working on animating an opening sequence for a project and trying to figure out a way to utilize .animate() in order to have my div "come in" from the right rather than the left, which appears to be the default direction.

I'm confident that there is a straightforward solution to this issue. Below is the code I've been using along with a link to the JSFiddle:

JSFiddle

$("#clickMe").click(function() {
    $(".login").animate({width: '0'});
}, function() {
    $(".login").animate({width: '100'});
});

Any help or suggestions would be greatly appreciated. Thank you!

One technique is to apply a margin-left equal to the element's width and animate it simultaneously. This method causes the width animation to appear shifted due to the margin adjustment.

$("#clickMe").click(function() {
  $(".login").animate({
    'width': '100',
    'margin-left': '0'
  });
});

.login {
  height: 100px;
  width: 0px;
  background-color: #f00;
  margin-left: 100px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="clickMe">
  Click To Change Size
</button>
<div class="login"></div>

Another option is to float the element to the right within a parent element of identical dimensions:

$("#clickMe").click(function() {
  $(".login").animate({width: '100%'});
});

.animation-wrapper {
  width: 100px;
  height: 100px;
}
.login {
  height: 100%;
  width: 0;
  background-color: #f00;
  float: right;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="clickMe">
  Click To Change Size
</button>
<div class="animation-wrapper">
  <div class="login"></div>
</div>

Alternatively, you can animate the left property and conceal the overflow:

$("#clickMe").click(function() {
  $(".login").animate({'left': '0'});
});

.animation-wrapper {
  position: relative;
  height: 100px;
  width: 100px;
  overflow: hidden;
}
.login {
  height: 100%;
  width: 100%;
  background-color: #f00;
  position: absolute;
  left: 100%;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="clickMe">
  Click To Change Size
</button>
<div class="animation-wrapper">
  <div class="login"></div>

Answer №2

Here is a straightforward solution that should suffice for simpler scenarios:

Enclose your login section within a container of specific width and height:

<div class="wrapper">
  <div class="login-section"></div>
</div>

Next, add the following styles:

.login-section {margin-left: 100px; height: 100px; width: 100px; background-color: red;}
.wrapper{
  width: 100px;
  height: 100px;
  overflow: hidden;
}

To shift your .login-section to the right within the .wrapper (using margin-left:100px;) and hide it with overflow:hidden from view, you can later reset the margin-left value to 0:

$("#clickButton").click(function() {
    $(".login-section").animate({marginLeft: 0});
});
