To create a custom header that appears on all pages throughout the site, place a file named _header.html in any module you will include in your server. Place it at the following location:
The header is written in HTML and the <body> section can render any kind of content, including links, images, and scripts. It is also responsible for its own formatting, dependencies, and resources.
The following _header.html file adds a simple message across the top, next to the logo. Create a new .html file in the location described above. This content will give you a simple starting place.
<span class="fa fa-flag"></span> <b>This is a custom header - from the footerTest module</b> <span class="fa fa-flag"></span>
In this example, the header file was placed in the resources/views directory of a "footerTest" module created in our development test environment. If _header.html files are defined in several modules, you will be able to select which module's definition
The header region is across the top of the page. Your content will appear to the right of the logo.
