Add symbols before/after facts values

To add a symbol before the fact values:

.fact-value::before {
   content: '%';
}

To add a symbol after the fact values:

.fact-value::after {
    content: '%';
}

To add a symbol before a specific fact:

.facts-area .fact:nth-of-type(1) .fact-value::before {
    content: '%';
}

To add a symbol after a specific fact:

.facts-area .fact:nth-of-type(1) .fact-value::after {
    content: '%';
}

Tip: Change the (1) value to the position of the fact you want to target. Change the % symbol to the symbol you actually want to use.
