TYPO3 Fluid: Create a Fluid content template file

Create a file called "main_1_column_with_menu.html" and put it in the "/fileadmin/templates" folder.
The file content will look like this:

<div id="content">
    <div id="content_menu">
        <f:cObject typoscriptObjectPath="lib.content_menu" />
    </div>
    <div id="content_main">
        <f:format.raw>{content_main}</f:format.raw>
    </div>
    <div class="clearer"></div>
</div>

There are 2 pieces of Fluid code in here. The first piece tells the Fluid engine to get content from the typoscript content object "lib.content_menu" and put it in the content_menu div. The second piece gets content from the content_main Fluid variable. This content typically comes from the TYPO3 backend, which you will put in later, and will be put in the content_main div. Please note that you can replace <f:format.raw>{content_main}</f:format.raw> with a short notation: {content_main -> f:format.raw()}. Both do the same job.

Please note: if you use TYPO3 v10, leave out the first piece of Fluid code (i.e. <f:cObject .../>). It will result in an error if you try to load the website without the actual typoscript content object.

Next, create a backend layout ->
