I have already researched and tried stuff like transform skew or border manipulation. But i can t really achieve the view like i want to. Is any CSS pro here ? Would be nice. ps - if a bootstrap solution exists would also help me.




Use a linear-gradient

* {
  margin: 0;
  psdding: 0;
div {
  height: 100vh;
  width: 100vw;
  background-color: blue;
  background-image: linear-gradient(10deg, lightblue 50%, transparent 50%), linear-gradient(-60deg, brown 30%, transparent 30%);
