Welcome to WordPress. This is your first post. Edit or delete it, then start writing!
The @if block conditionally displays its content when its condition expression is truthy:
@if (a > b) { <p>{{a}} is greater than {{b}}</p>}check
If you want to display alternative content, you can do so by providing any number of @else if blocks and a singular @else block.
@if (a > b) {
{{a}} is greater than {{b}}
} @else if (b > a) {
{{a}} is less than {{b}}
} @else {
{{a}} is equal to {{b}}
}
