how to create and edit a template

[4NN1H1L4710N 3]

Hello guys
I use the invision community suite software as my forum software and all of my threads use the same "template" code, see below.
The data in the class "CP_content" e.g. "Operating system:" is always the same and the data in the class "CP_content_info" e.g. "All Win10 versions" is different in every thread.
Now I have over 100 threads and when I want to change something like "Operating system:" to "OS:" or add something new, I have to change all threads one by one and this is very very time consuming.
I want to use something like a single template file, edit it and all threads update to the new changes of the template file. Is this possible with css or can you recommend me what I should be doing?
I am a beginner and I have not found in google how to achieve my thoughts because I am not sure what to look for.

This is my code

<table style="table-layout: fixed; width: 700px">
    <colgroup>
        <col style="width: 140px">
        <col style="width: 160px">
        <col style="width: 140px">
        <col style="width: 260px">
    </colgroup>
    <tbody>
        <tr>
            <td colspan="4">
                <span class="CP_topic"><span class="ipsEmoji"></span> DETAILS</span>
            </td>
        </tr>
        <tr>
            <td>
                <span class="CP_content">Release date:</span>
            </td>
            <td>
                <span class="CP_content_info">01/2020</span>
            </td>
            <td>
                <span class="CP_content">Operating system:</span>
            </td>
            <td>
