Shopify: Turn Individual Code to HTML

I need a liquid code that turns the following "fake page code" of my individual page into a nice HTML page.

This is an example of another similar code:

{% if page.content contains '[tab]' %}
{% for desc in fulldesc %}
{% if counttab > 1 %}
{% assign desc_h = desc | split: '[/tab]' | first %}
<div class="acc__card">
<div class="acc__title">{{ desc_h | split: '[/tab_h]' | first | remove: '[tab_h]' | strip_html }}</div>
<div class="acc__panel">
{{ desc_h | split: '[/tab_h]' | last }}
</div>
</div>
{% endif %}
{% assign counttab = counttab | plus: 1 %}
{% endfor %}
{% endif %}

Please offer a fixed price. I do not respond to placeholders.
