What I learned

I learned a lot about styling images and form validation. I encountered a lot of challenges in the completion of this project but i am happy with the progress i have made so far.

<div class="thank-you hidden">
  <div class="content">
    <img src="images/icon-complete.svg" alt="" />
    <h1>THANK YOU!</h1>
    <p>We've added your card details</p>
    <button class="continue">Continue</button>
  </div>
</div>

This is the thankyou page html

function confirm(inputs) {
  let allFilled = true;
  inputs.forEach((input) => {
    const formControl = input.parentElement;
    if (input.value === '') {
      formControl.classList.add('error');
      allFilled = false;
    } else if (formControl.className.includes('error')) {
      allFilled = false;
    } else {
      formControl.classList.remove('error');
    }
  });

  if (allFilled) {
    form.classList.add('hidden');
    thankYou.classList.remove('hidden');
  }
}

Continued development

I want to continue improving my skills on using local storage.
