How can I create a unique CSS or JS transition for a button that dynamically changes size based on text

Question

How can I create a unique CSS or JS transition for a button that dynamically changes size based on text

My Angular app features a button labeled with "+".

When the user hovers over it, I use

element.append(' Add a New Number');

to add the text "Add a New Number" next to the + sign in the label.

Upon clicking the button, a new number is added and the label reverts back to "+".

I want to animate either the change in button size or the text label change. However, applying a CSS transition to width has shown no effect so far.

Any ideas?

UPDATE: Just to clarify, this is a bootstrap input group button. I'm trying to avoid setting specific widths or using CSS transforms to prevent any issues with the button display at different screen sizes.

Here are the two states:

I was hoping that by injecting more words, the existing button would naturally stretch.

It seems like you may not have a predefined width, but you can still achieve the desired effect by utilizing transform-origin and scale.

Check out the FIDDLE HERE

Here is an example of the HTML:

<button id="btn">Click</button>

And here is the CSS code:

#btn {
    outline: none;
    border:none;
    background: orange;
    padding: 1em 1.5em;
    -webkit-transition: .3s;
    -o-transition: .3s;
    transition: .3s;
}
#btn:hover {
    -webkit-transform: scaleX(1.2);
    -ms-transform: scaleX(1.2);
    -o-transform: scaleX(1.2);
    transform: scaleX(1.2);
    -webkit-transform-origin:0 0;
    -moz-transform-origin:0 0;
    -ms-transform-origin:0 0;
    -o-transform-origin:0 0;
    transform-origin:0 0;
}

Instead of using properties like width, it's recommended to utilize CSS transforms for smoother animations. If there are any slight jerks in the animation, further refining may be needed.

If you have jQuery tagged, this is how I would approach it.

Utilizing all transitions - fading and animating

function updateButtonText(button, text){
    // Using jQuery
    $button = $(button);
    
    // Store original CSS properties
    oldTextAlign = $button.css('text-align');
    overflowValue = $button.css('overflow');
    whiteSpaceValue = $button.css('white-space');
    $button.css('text-align', 'left').css('overflow', 'hidden').css('white-space', 'nowrap');
    
    // Determine the new width first
    $tmpBtn = $button.clone().append(text).css('opacity', '0.0').appendTo('body');
    newWidth = $tmpBtn.outerWidth();
    $tmpBtn.remove();
    
    // Expand the button to fit the new width
    $button.animate({width: newWidth+"px"});
    
    // Fade the new text into the button
    $button.append('<span style="display:none">'+text+'</span>');
    $btnText = $button.find('span').fadeIn('slow');
    
    return {
        'text-align': oldTextAlign,
        'overflow': overflowValue,
        'white-space': whiteSpaceValue
    };
}

Utilizing bootstrap CSS and Angular together may seem complex, but here is a programmatic approach to tackle it. A directive can be built to smoothly integrate with Angular and handle the model and data differently:

HTML

<div class="thing">+ <span id="message">
    <span id='target'></span>
</span></div>

JavaScript

$('.thing').hover( function() {
  var originalWidth = $(this).outerWidth();
  $messageHolder = $(this).find('#message');
  $target = $(this).find('#target');
  $target.text('Some helpful text');
  var targetWidth = $target.outerWidth();
  $messageHolder.animate({
    width: targetWidth
  }, {
    duration: 200,
    complete: function() {
      $messageHolder.animate({
        opacity: 1
      }, 500);
    }
  });
});

$('.thing').on('click', function() {
  $target = $(this).find('#target');
  $target.empty();
  $messageHolder = $(this).find('#message');
  $messageHolder.animate({
    opacity: 0
  }, {
    duration: 200,
    complete: function() {
      $messageHolder.animate({
        width: 0
      }, 200);
    }
  });

});

Angular's ng-animate library likely observes the dom and offers a smooth way of animating changes in the model/controller. This could be a glimpse of what happens behind the scenes.

Best of luck!
