Hi,

You can customize Matomo by creating Plugins and Themes.

See
https://developer.matomo.org/guides/distributing-your-plugin
and
https://developer.matomo.org/guides/theming

You can also change the main image in the general settings

Hello, Thank you for the link, in fact the theme, but it does not offer me the option to add a banner image.
so I made these changes:

1- add a title
2- add a banner image
3- change the colors of the icons

While with the theme I only change the colors.

Thank you.

Hi,

Changing the colors is possible as described in the theme guide (and by adding custom CSS/overwriting LESS variables).

Changing the template is a bit more complex, but you can override any template file (.twig) in Matomo in your theme:

Hi,
I dont know if i have the same version as the article , here is my
image

i tried to add some code into the “index.twig”

{% include "@Dashboard/_header.twig" %}
<div class="top_controls"><div class="new_banner"><span class="banner"></span><div>
    {% include "@CoreHome/_periodSelect.twig" %}
    {{ postEvent("Template.nextToCalendar") }}

and the css of those new classes in the dashboard.less:

span.banner {
    height: 121px;
    width: 1137px;   
	background: url(plugins/Morpheus/images/banniere1.png) no-repeat;
    margin: 0px auto;
    display: block;
}
.new_banner {
    min-width: 1260px;
    background: #4ab4e6;
}

it doesnt work !
