Answer 5

The part from my css code where I make the structure:

.body{
display: grid;
width: 100%;
grid-template-rows: 20% 20% 20% 20% 20%;
grid-template-columns: 20% 20% 20% 20% 20%;
border-style: none;
}

.header{
grid-column-start: 1;
grid-column-end: 6;
}

.informationsStructure{
grid-column-start: 1;
grid-column-end: 6;
padding-left: 5%;
padding-right: 5%;
}

.Course{
grid-column-start: 1;
grid-column-end: 6;
padding-left: 5%;
padding-right: 2%;
}
