Screenshot of the page:

Im trying to achieve something like:

.box {
    border-style: groove;
    width: 100px;
    height: 100px;
    transform: rotate(45deg);
}

Here is a demo taken from my article: https://css-tricks.com/hexagons-and-beyond-flexible-responsive-grid-patterns-sans-media-queries/

You can find all the detail there:

.main {
  display:flex;
  --s: 100px;  /* size  */
  --m: 4px;    /* space */
  --r: calc(var(--s)   4*var(--m) - 2px);
}

.container {
  font-size: 0;
}

.container div {
  width: var(--s);
  margin: var(--m);
  height: var(--s);
  display: inline-block;
  font-size:initial;
  clip-path: polygon(50% 0, 100% 50%, 50% 100%, 0 50%);
  background: red;
  margin-bottom: calc(var(--m) - var(--s)*0.5);
}
.container div:nth-child(odd) {
  background:green;
}
.container::before {
  content: "";
  width: calc(var(--s)/2   var(--m));
  float: left;
  height: 140%;
  shape-outside: repeating-linear-gradient(     
                   #0000 0 calc(var(--r) - 3px),      
                   #000  0 var(--r));
}

<div class="main">
  <div class="container">
    <div></div>
    <div></div>
    <div></div>
    <div></div>

You can also update it like below to use transform and add border

.main {
  display:flex;
  --s: 100px;  /* size  */
  --m: 4px;    /* space */
  --r: calc(var(--s)   4*var(--m) - 2px);
}

.container {
  font-size: 0;
}

.container div {
  width: var(--s);
  margin: var(--m);
  height: var(--s);
  display: inline-block;
  font-size:initial;
  transform:rotate(45deg) scale(0.707);
  border:2px solid;
  box-sizing:border-box;
  margin-bottom: calc(var(--m) - var(--s)*0.5);
}

.container::before {
  content: "";
  width: calc(var(--s)/2   var(--m));
  float: left;
  height: 140%;
  shape-outside: repeating-linear-gradient(     
                   #0000 0 calc(var(--r) - 3px),      
                   #000  0 var(--r));
}

<div class="main">
  <div class="container">
