Changing the height of a table row using CSS transitions

I need help with a CSS table that has rows of the same height. I want to make it so that when a user clicks on one row, that row expands to fill the entire table height while the other rows fade away. I originally had this working by setting display:none on the other rows, but now I'd like to incorporate transitions for a smoother effect.

I've experimented with setting max-height to 100% and then transitioning it to 0, but this only slightly enlarges the selected row while leaving the others in place. I also tried changing the height from 100% to 0, but this resulted in the top row becoming massive and the rest shrinking down to about 15px tall.

Ultimately, I'm looking to smoothly transition between height:auto and height:0, but I haven't been successful in achieving this on a table row. Any suggestions on how to accomplish this transition effectively?

Answer №1

After conducting a brief search on Google, I came across this:

.custom_section {
    /* Initially no height and contents hidden */
    max-height: 0;
    overflow: hidden;

    /* Transitions setup */
    -webkit-transition: max-height 0.8s;
    -moz-transition: max-height 0.8s;
    transition: max-height 0.8s;
}
.container:hover .custom_section {
    /* On hover, set the max-height to a specific value */
    max-height: 200px;
}

To implement this, you will need to adjust the classes and use JavaScript click events. Consider adding fade and resize effects for smoother animations.

tr {
  max-height: 0;
  overflow: hidden;
  -webkit-transition: max-height 360ms;
}

tr.selected {
    -webkit-animation:
    grow 420ms ease-in-out,
    fadeIn 540ms ease-in;
}
tr.deslection {
  -webkit-animation:
    shrink 420ms ease-in-out,
    fadeOut fadeIn 540ms ease-out;
}


@-webkit-keyframes grow {
  0% {
    max-height: /*initial row height*/;
  }
  100% {
    max-height: /*new row height*/;
  }
}
@-webkit-keyframes fadeIn {
  0% {
    opacity: 0;
  }
  100% {
    opacity: 1;
  }
}
@-webkit-keyframes shrink {
  0% {
    max-height: /*new row height*/;
  }
  100% {
    max-height: /*initial row height*/;
  }
}
@-webkit-keyframes fadeOut {
  0% {
    opacity: 1;
  }
  100% {
    opacity: 0;
  }
}

Based on your understanding of adding/removing classes with JavaScript, I assume you can handle that part. Feel free to share some code if you require further assistance. Best of luck!
