Frontend Mentor - Intro component with sign up form solution

Overview

The challenge

Users should be able to:

  • View the optimal layout for the site depending on their device's screen size
  • See hover states for all interactive elements on the page
  • Receive an error message when the form is submitted if:
    • Any input field is empty. The message for this error should say "[Field Name] cannot be empty"
    • The email address is not formatted correctly (i.e. a correct email address should have this structure: name@host.tld). The message for this error should say "Looks like this is not an email"

My process

Built with

  • Semantic HTML5 markup
  • CSS custom properties
  • Flexbox
  • Mobile-first workflow
  • email verification

What I learned

  • good practice with email verification using Javascript

  • if email address formatted incorrectly, error messages appear

  • if email address formatted correctly, error messages disappear

  • used onkeydown function in html then connected it through javascript

<input type="email" required="required" id="email" placeholder="Email Address" onkeydown="validation()"/> <small class="error-message" id="email-error-msg">Looks like this is not an email</small><br />
  • styling error classes and ensuring they work/display the correct way requires more attention to detail, which is why i'm proud of how I named and styled these
.error-icon { background-image: url(./images/icon-error.svg); background-repeat: no-repeat; background-position-x: 95%; background-position-y: center; } .error-message { visibility: hidden; color: red; text-align: right; font-style: italic; } /* error class for javascript*/ .error-border { border: solid 1px red; } .invalid { border: solid 1px red; }

Continued development

  • still need more practice with variations of form validation and regex so I dont have to look up the process every single time
