When viewed on mobile devices, two 100vh sections are overlapping each other

Question

When viewed on mobile devices, two 100vh sections are overlapping each other

My goal is to create two sections that fill the entire viewport height in the browser. The code below is functioning properly on the desktop version. However, on mobile devices, the content of section two (consisting of 3 bootstrap columns with text) is overlapping with section one. How can I modify my code to prevent this overlap?

body {
  color: #FFF;
}

#slide1 {
  background-color: grey;
  width: 100vw;
  height: 100vh;
}

#slide2 {
  background-color: blue;
  width: 100vw;
  height: 100vh;
}

Recommendation: Use the CSS property min-height instead of height and adjust the centering as shown below. You can also eliminate the width:100vw as it is unnecessary since your elements are block elements by default.

body {
  color: #FFF;
}

#slide1 {
  background-color: grey;
  min-height: 100vh;
}

#slide2 {
  background-color: blue;
  min-height: 100vh;
}
