Create Color Guessing Game Using JavaScript

Welcome to Code With Random blog. In this blog, We learn how we create Color Guessing Game Using HTML, CSS, and JavaScript.

You have to predict the colors that will emerge from the combination of primary colors in this game of color prediction. This game seeks to increase a person’s ability to predict colors by randomly generating a color each time and piques their curiosity about the potential color that could result from a random combination of primary colors.

I hope you enjoy our blog so let’s start with a basic HTML structure for Color Guessing Game.

CSS Code For Color Guessing Game

body {
background-color: #232323;
margin: 0;
font-family: "Montserrat", "Avenir";
}
.square {
width: 30%;
background: purple;
padding-bottom: 30%;
float: left;
margin: 1.66%;
border-radius: 15%;
transition: background 0.6s;
-webkit-transition: background 0.6s;
-moz-transition: background 0.6s;
}
#container {
margin: 20px auto;
max-width: 600px;
}
h1 {
text-align: center;
line-height: 1.1;
font-weight: normal;
color: white;
background: steelblue;
margin: 0;
text-transform: uppercase;
padding-top: 20px;
padding-bottom: 20px;
}
#colorDisplay {
font-size: 200%;
}
#stripe {
background: white;
height: 30px;
text-align: center;
color: black;
}
.selected {
color: white;
background: steelblue;
}
button {
border: none;
background: none;
text-transform: uppercase;
height: 100%;
font-weight: 700;
color: steelblue;
letter-spacing: 1px;
font-size: inherit;

outline: none;
}
#message {

}
button:hover {

background: steelblue;
}

Step1:We will first set the background to “black” using the body element selector, and we will set the margin to “30 px” using the margin property. We will also change the font family to “Montserrat” using the font-family property.

body {
    background-color: #232323;
    margin: 0;
    font-family: "Montserrat", "Avenir";
}

Step2:Now, using the class selector property (.square), we will set the breadth to 30%, the background color property to “purple” to set the background color of our square tiles, and the padding bottom property to 30% to set the bottom padding. The border radius will now be adjusted to 15% using the border radius property.

.square {
    width: 30%;
    background: purple;
    padding-bottom: 30%;
    float: left;
    margin: 1.66%;
    border-radius: 15%;
    transition: background 0.6s;
    -webkit-transition: background 0.6s;
    -moz-transition: background 0.6s;
}

Step3:Using the #Id number, the container will now be chosen. Following that, the maximum width property will be used to set the maximum width to 600 px, and the border property will be set to 20 px auto.

Now using the h1 tag selector, using the text-align property, we will set the text alignment as “center”; using the line height property, we will set the line height as “1.1”; using the color property, we will set the font color as “White”; and using the background color property, we will set the background as “Steel Blue”. The styling will also be applied to the buttons and other game components.

#container {
    margin: 20px auto;
    max-width: 600px;
}

h1 {
    text-align: center;
    line-height: 1.1;
    font-weight: normal;
    color: white;
    background: steelblue;
    margin: 0;
    text-transform: uppercase;
    padding-top: 20px;
    padding-bottom: 20px;
}

#colorDisplay {
    font-size: 200%;
}

#stripe {
    background: white;
    height: 30px;
    text-align: center;
    color: black;
}

.selected {
    color: white;
    background: steelblue;
}

button {
    border: none;
    background: none;
    text-transform: uppercase;
    height: 100%;
    font-weight: 700;
    color: steelblue;
    letter-spacing: 1px;
    font-size: inherit;
    transition: all 0.3s;
    -webkit-transition: all 0.3s;
    -moz-transition: all 0.3s;
    outline: none;
}

#message {
    display: inline-block;
    width: 20%;
}

button:hover {
    color: white;
    background: steelblue;
}

}

We will first use the document to pick all of the HTML elements inside of our javascript. technique of queryselector We will use the id to select the html elements, and then we will make some variables using the var keyword. Finally, we will add a click event to our guessing game using the easyBtn.addEventlistener, and we will use the click event to add and remove the classlist. The user will then point to each as they correctly predict the answer after we first create the random color using the math.random function using the colordisplay property.
