Hi,

To make the SVG and image appear on every page:

1. Move them outside the main content div.

2. Put the SVG in a div with the class "header".

3. Put the image in a div with class "footer".

4. Keep your main content in the div with class "page".

5. Use position: absolute instead of fixed.

For example,use the following xml code as reference:

<t t-call="web.basic_layout">
    <!-- Header div for the SVG -->
    <div class="header">
        <div t-attf-style="position: absolute; top: 0; right: 0; width: 330px; height: 160px;">
            <!-- Your SVG code here -->
        </div>
    </div>

    <!-- Footer div for the image -->
    <div class="footer">
        <div t-attf-style="position: absolute; bottom: 0; left: 0;">
<img t-att-src="'/path/to/your/image'"/>
        </div>
    </div>

    <!-- Main content -->
    <div class="page">
        <!-- Your main content (tables, etc.) goes here -->
    </div>
</t>

Hope it helps.
