Overview

The challenge

Users should be able to:

• Go back to a previous step to update their selections
• See a summary of their selections on the final step and confirm their order
• View the optimal layout for the interface depending on their device's screen size
• See hover and focus states for all interactive elements on the page
• Receive form validation messages if:
  • A field has been missed
  • The email address is not formatted correctly
  • A step is submitted, but no selection has been made

My process

What I learned

1. You can change the placeholder's text color with "::placeholder" in css:

::placeholder{
    color:hsl(231, 11%, 63%) ;
}

2. If the user forgot to input one of the following then it would trigger a flag response to equal 0.

if(namee.value==""){
        document.querySelector(".name-error").style.display="block";
        document.querySelector(".name-input").style.border="1px solid hsl(354, 84%, 57%)";
        input_error_flag = 0;
    }
    if(email.value == ""){
        document.querySelector(".email-error").style.display="block";
        document.querySelector(".email-input").style.border="1px solid hsl(354, 84%, 57%)";
        input_error_flag = 0;
    }
    else if(!isEmail(email.value)) {
        document.querySelector(".email-error").innerHTML="Please enter a valid email";
        document.querySelector(".email-error").style.display="block";
        document.querySelector(".email-input").style.border="1px solid hsl(354, 84%, 57%)";
        input_error_flag = 0;
    }
    if(phone.value==""){
        document.querySelector(".phone-error").style.display="block";
        document.querySelector(".phone-input").style.border="1px solid hsl(354, 84%, 57%)";
        input_error_flag = 0;
    }

3. You can remove arrow keys from input type number with:

input[type=number]::-webkit-inner-spin-button, 
input[type=number]::-webkit-outer-spin-button {
    appearance: none;
}

But for Mozilla it only works if you add the following code:

input[type=number] {
    -moz-appearance: textfield;
}

which also generates an error highlight on visual studio code recommending us not to use it because it's nonstandard.

Before noticing that there was an already resized mobile background picture I tried to figure a way of resizing the already existing desktop background picture so only the desired part shows. I learned that you can "crop" an image by using:

img-test{
object-fit: cover; 
object-position: -20% 0;
}

Line height should be set to 100% so all the padding comes from the button settings instead of the text

button{
  line-height: 100%;
}
