  }

@supports (display: grid) {
/* Code that will only run if the selector is supported */
   main {
    display: grid;
  }
}

Improve Media Defaults

Images are inline elements, and by setting the default value to display:block; we can avoid many potential issues. Setting max-width:100%; we prevent images from overflowing when they are in a container that is not wide enough to contain them.

img, picture, video, svg {
  display: block;
  max-width: 100%;
  object-fit: contain;
}

Additionally, I have set object-fit:contain; to ensure that images preserve a nice aspect ratio.

Style :optional Form Elements

You can style form fields like input, select, and textarea that do not have a required attribute on them using the :optional pseudo-class.

/* Selects all optional form fields on the page */
*:optional{
  background-color: green;
}

Note: Use :required pseudo-class to select required form fields.

The Custom Cursor

Five Ways of Centering Divs

.parent{
  display: grid;
}
.child{
  margin: auto;
}

/* 3.Centering with positioning */
div{
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%,-50%);
}

/* 4.Centering with flexbox  */
.parent{
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
}

/* 5.Centering with flexbox & margins */
.parent{
  display: flex;
