Title Alignment Off Centre

Question

I am writing this code, first webpage I have built. I have learning along the way but I have hit a block, I feel like it may be a simple block but in my 'scallop' H1 & P I can't get them the align centre, they keep sitting to the left of my site. Can anybody see any faults I am missing?

.topnav {
  overflow: hidden;
  width: 100%;
  max-height: 100px;
  background-color: #e2bdf9;
}

.topnav a {
  color: #1a0342;
  text-align: center;
  display: inline-block;
  padding: 14px 16px;
  text-decoration: none;
  font-size: 17px;
  font-family: "Lilita One", cursive;
}

.topnav a:hover {
  background-color: #ddd;
  color: black;
}

.topnav a.active {
  background-color: rgb(255, 88, 5);
  color: white;
}

.TitleHeading {
  position: relative;
  max-width: 50%;
  max-height: 150px;
  left: -0.5px;
  bottom: 354px;
  background-color: rgb(9, 158, 123);
  color: white;
  padding-left: 20px;
  padding-right: 20%;
  padding-top: 100px;
  padding-bottom: 100px;
  float: left;
  width: 300px;
}

.firstbreak {
  width: 100%;
  height: 50px;
  border: none;
  background-color: #e2bdf9;
}

.scallop {
  position: relative;
  background: #e26464;
  padding: 50px;
}

.scallop h1 {
  position: relative;
  text-align: center;
  color: white;
  font-size: 35px;
  text-transform: uppercase;
  font-family: "PT Sans Narrow", sans-serif;
  line-height: 50px;
}

.scallop p {
  position: relative;
  text-align: center;
  color: white;
}

.scallop::after {
  position: absolute;
  bottom: -50px;
  left: 0px;
  width: 100%;
  content: " ";
  background: radial-gradient( circle at 50% 0%, #e26464 25%, #c4dcd1 26%, #c4dcd1 40%);
  background-color: #e26464;
  background-size: 50px 100px;
  height: 50px;
  background-repeat: repeat-x;
}

.after-scallop {
  background: #c4dcd1;
  padding: 50px;
  margin-bottom: 50px;
}

.after-scallop p {
  color: #9089c0;
  font-size: 25px;
  text-transform: none;
  font-family: "PT Sans Narrow", sans-serif;
  text-align: center;
  margin-top: 30px;
  font-weight: bold;
}

a {
  text-decoration: none;
}

img {
  margin-right: 20px;

Can anyone identify where I have gone wrong?

Answer 1

You need to change the position of the .scallop class to absolute. Then your scallop text will be center.

Answer 2

The problem is with the float:left of the .TitleHeading element. It is moved out of the way, due to the bottom: 354px but the space it occupied initially is not, so it affects the following elements. I would suggest skipping the float completely and try to use flex/grid for structuring the layout of the page.
