Remember those Valentine's Candy Conversation hearts? For this project I'm recreating them using vanilla JavaScript and CSS.
Last year I added pre-made messages from a list. This time I'll show how to use user input to create a message.
I'll use the same CSS heart from the original post. I'll changed the background to purple on the user input version.
Draw a heart
If we're going to write on a heart we need to build the heart first. This is made with some basic shapes, a square and two circles. To make a CSS Circle you make a square and give it a border radius of 50%.
I added borders so you can see the individual shapes.
/* The circles */
.bigheart:before, .bigheart:after {
position: absolute;
background-color: var(--heart-red);
width: 400px;
height: 400px;
content: '';
-webkit-border-radius: 50%;
-moz-border-radius: 50%;
-o-border-radius: 50%;
border-radius: 50%;
}
/* moving the circles */
.bigheart:before {
bottom: 0;
left: -200;
}
.bigheart:after {
top: -200px;
right: 0;
}
/*Rotate the whole thing */
.bigheart {
-webkit-transform: rotate(45deg);
-moz-transform: rotate(45deg);
-ms-transform: rotate(45deg);
-o-transform: rotate(45deg);
transform: rotate(45deg);
}
Once the shapes are made, transform: rotate(45deg)
turns the heart so the point is straight down. A drop shadow is added to make the heart standout from the background.
The Messages
I used an input box for a user to enter a message. It appears on screen as a user types. The ID of heart is targeted using getElementById
.
<div class="login-screen">
<h1>"Hello There!"</h1>
<input placeholder="Enter a message." name="message" />
</div>
.
.
.
<!-- Messages displays Here -->
<div class="quote-screen" id="heart">
const input = document.querySelector('input');
const enteredInput = document.getElementById('heart');
input.addEventListener('input', userMessage);
function userMessage(e) {
enteredInput.textContent = e.target.value;
}
Wrap-up
This was silly and not practical. The biggest problem I had was I forgot to add display to the heart CSS. So the text was not on screen.
