Backface-visibility and 3D transforms practice


by Jeremy Caudle
notes

I've never used the backface-visibility property before and I've rarely done any 3d transformations as well. Today's a good day to give them a try.

This paragraph should be visible and display off to the side before moving.

View the code:

HTML and JS 
<div class="codedoodle-block">
        <div class="card">
            <label for="checkbox">Toggle animation</label><input name="checkbox" id="checkbox" class="hide" type="checkbox" />
            <p>This paragraph should be visible and display off to the side before moving.</p>
            <label for="checkbox2">Toggle animation</label><input name="checkbox" id="checkbox2" class="hide" type="checkbox" />
            <p class="hidden">This paragraph should be hidden and display only after it has started animating.</p>

        </div>
</div>
