Center text inside a Div box 20px from bottom edge-CodePudding

I have a beige Div box that responds to the window size, it's always x amount distant from window borders, check webpage:

CodePudding user response：

After giving position fixed property to h5 and specifying the position, you can adjust the size of the text with @media according to the screen size.

body {
  background: white;
  padding: 0;
  margin: 0;
  display: flex;
  height: 100vh;
}

div {
  width: calc(100% - 40px);
  height: calc(100% - 40px);
  background: #f0e8e6;
  overflow: hidden;
  margin: auto;
  display: flex;
}

img {
  position: absolute;
  top:50%;
  left:50%;
  transform:translate(-50%, -50%);
  width:calc(100% - 40px);
  height:calc(100% - 40px);
  max-width:40vw;
  object-fit:contain !important;
}
h5{
  position:fixed;
  bottom:0;
  left:50%;
  transform:translatex(-50%);
  font-size:1.5rem;
  line-height: 1.5rem;
}
@media screen and (min-width:768px){
   h5{
    bottom:20px;
    font-size:0.8rem;
    line-height: 0.8rem;
  }
}
