##
CSS Styling
The CSS file defines the visual appearance of the project, emphasizing a dark theme with clear, user-friendly controls. Key styling elements include:
###
Global Styles
The `body` and `html` elements are styled to occupy the full height of the viewport, with a black background and white text for a high-contrast look. The font-family is set to ‘Courier New’, giving the project a classic, retro feel.
“`css
html, body {
height: 100vh;
margin: 0;
background: black; /* Pure black background */
color: white; /* White text for contrast */
font-family: ‘Courier New’, monospace; /* Retro feel */
display: flex;
justify-content: center;
align-items: center;
flex-direction: column; /* Vertical alignment */
}
“`
###
Header
The header element is centered horizontally and positioned at the top of the page, with white text to stand out against the dark background.
“`css
header {
text-align: center;
margin-bottom: 20px;
}
“`
###
Control Panel
The control panel is positioned at the bottom of the page and centered horizontally, with buttons styled to be visually appealing and easy to interact with. Buttons have a semi-transparent white background that changes on hover to provide visual feedback.
“`css
#controlPanel {
position: absolute;
bottom: 20px;
display: flex;
justify-content: center;
gap: 10px; /* Space between buttons */
}
button {
background-color: rgba(255, 255, 255, 0.2); /* Semi-transparent white */
color: white;
border: none;
padding: 10px 20px;
cursor: pointer;
border-radius: 5px;
transition: background-color 0.3s ease;
}
button:hover {
background-color: rgba(255, 255, 255, 0.5); /* Change on hover */
}
“`
###
Canvas
The canvas element is centered both horizontally and vertically within the main section, with dimensions set to fit the majority of the viewport.
“`css
#psychCanvas {
display: block;
margin: auto;
background-color: black;
border: 2px solid white;
}
“`
###
Modal
The instructions modal is styled to cover the entire viewport with a semi-transparent black background, focusing attention on the instructions. The modal content is centered and styled with a black background and white text, with a close button for easy dismissal.
“`css
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
left: 0;
top: 0;
width: 100%;
height: 100%;
overflow: auto; /* Enable scroll if needed */
background-color: rgba(0,0,0,0.8); /* Black w/ opacity */
}
.modal-content {
background-color: black;
margin: 15% auto; /* 15% from the top and centered */
padding: 20px;
border: 1px solid #888;
width: 80%; /* Could be more or less, depending on screen size */
}
.close-button {
color: white;
float: right;
font-size: 28px;
font-weight: bold;
}
.close-button:hover,
.close-button:focus {
color: #aaa;
text-decoration: none;
cursor: pointer;
}
“`
##
JavaScript Functionality
The JavaScript file drives the interactivity and animation of the project, enabling users to customize the wave patterns. Key functionalities include:
###
Canvas Setup
The script initializes the canvas context and sets up parameters for the wave animation.
“`javascript
const canvas = document.getElementById(‘psychCanvas’);
const ctx = canvas.getContext(‘2d’);
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;
“`
###
Wave Animation
The script generates and continuously updates the wave patterns based on mathematical functions, creating a dynamic visual effect. Different wave styles, amplitudes, frequencies, and colors can be adjusted through user interactions with the control buttons.
“`javascript
let amplitude = 100;
let frequency = 0.01;
let waveStyle = ‘sine’;
function drawWave() {
ctx.clearRect(0, 0, canvas.width, canvas.height);
ctx.beginPath();
ctx.moveTo(0, canvas.height / 2);
for (let x = 0; x < canvas.width; x++) { let y; if (waveStyle === 'sine') { y = amplitude * Math.sin(frequency * x + Date.now() / 1000); } else if (waveStyle === 'cosine') { y = amplitude * Math.cos(frequency * x + Date.now() / 1000); } ctx.lineTo(x, canvas.height / 2 + y); } ctx.strokeStyle = 'white'; ctx.stroke(); } setInterval(drawWave, 30); ``` ###
Control Buttons
Event listeners are added to
the control buttons to handle user interactions, allowing for real-time adjustments to the wave parameters.
“`javascript
document.getElementById(‘changeWave’).addEventListener(‘click’, () => {
waveStyle = waveStyle === ‘sine’ ? ‘cosine’ : ‘sine’;
});
document.getElementById(‘increaseAmplitude’).addEventListener(‘click’, () => {
amplitude += 10;
});
document.getElementById(‘decreaseAmplitude’).addEventListener(‘click’, () => {
amplitude -= 10;
});
document.getElementById(‘increaseFrequency’).addEventListener(‘click’, () => {
frequency += 0.001;
});
document.getElementById(‘decreaseFrequency’).addEventListener(‘click’, () => {
frequency -= 0.001;
});
document.getElementById(‘randomize’).addEventListener(‘click’, () => {
amplitude = Math.random() * 200;
frequency = Math.random() * 0.02;
});
document.getElementById(‘toggleGrid’).addEventListener(‘click’, () => {
// Functionality to toggle grid overlay
});
document.getElementById(‘showInstructions’).addEventListener(‘click’, () => {
document.getElementById(‘instructionsModal’).style.display = ‘block’;
});
document.querySelector(‘.close-button’).addEventListener(‘click’, () => {
document.getElementById(‘instructionsModal’).style.display = ‘none’;
});
“`
