I'm trying to make a color black and then a color white, but some colors come together horizontally, and I didn't want it to stay that way. I want to create a board from a loop.
Could anyone help?
var tab = document.querySelector('.grid-container')
for (let i = 1; i <= 64; i++) {
if (i % 3 == 0) {
tab.innerHTML += '<div class="grid-item black">'+i+'</div>'
} else {
tab.innerHTML += '<div class="grid-item white">'+i+'</div>'
}
}.grid-container {
display: grid;
grid-template-columns: repeat(8, 50px);
grid-template-rows: repeat(8, 50px);
background-color: #2196F3;
}
.grid-item {
background-color: rgba(255, 255, 255, 0.8);
border: 1px solid rgba(0, 0, 0, 0.8);
font-size: 30px;
text-align: center;
}
.black{
background-color: black;
}
.white {
background-color: white;

Then we can use the following if to check for black/white squares:
if ((i + j) % 2) {
tab.innerHTML += '<div class="grid-item black">'+n+'</div>'
} else {
tab.innerHTML += '<div class="grid-item white">'+n+'</div>'
}
var tab = document.querySelector('.grid-container')
for (let i = 0; i < 8; i++) {
for (let j = 0; j < 8; j++) {
let n = 1 + (i * 8 + j);
if ((i + j) % 2) {
tab.innerHTML += '<div class="grid-item black">'+n+'</div>'
} else {
tab.innerHTML += '<div class="grid-item white">'+n+'</div>'
}
}
}.grid-container {
display: grid;
grid-template-columns: repeat(8, 50px);
grid-template-rows: repeat(8, 50px);
background-color: #2196F3;
}
.grid-item {
background-color: rgba(255, 255, 255, 0.8);
border: 1px solid rgba(0, 0, 0, 0.8);

background-color: black;
