               font-family: var(--gk-body-font-family);
          }

          .headings {
               font-family: var(--gk-heading-font-family);

• Option 2: Select Tools > Web Developer > Inspector from the top menu bar.
• Option 3: Use the shortcut control-shift-C in Windows or command-option-C in macOS.

Step 2: add class to Selectors that use this font

Template colors

The brand colors are the major standard colors of Bootstrap. The brand colors are the color variables of Bootstrap, but already customized in each template, so when you change the color of one brand here, it will override the color of the corresponding color variables.

The brand color settings are in theme level, it means, if you are configuring for Template style A, the color settings will be applied for the pages that use the template style A only.

You can add as many color items as you want, set a default color for each user color item. Delete or change color label are processed in the Master template style only.

Layout settings

Supports multiple layouts by default. In each layout, it is built up with multiple blocks (header, mainbody_top, mainbody_bottom, sidebar-l, sidebar-r ...). Each block contains one or many module positions. You can assign specific module positions to a block.

Layout Configuration

In the layout part, there will be 2 parts to be configured: The Template Layout and the Sublayout Configuration.

Select Layout for style

In GK framework, each style will use one layout (but please keep in mind that one site use many styles » so one site can use multiple layouts simultaneously because GK framework use multiple styles simultaneously).

Subpage layout

Powerful layout builder in GK help you build flexible layouts for your website. In Layout setting, we added one more setting called: Subpage Layout.

What is subpage layout?

Subpage layout is the layout to use for subpages. This is to show the issue where user want to use a different layout for the main page and its sub-pages.

You have a blog menu with a list of blog articles on the page. In this case, the Blog menu is the main page and blog detail pages are a sub-page of blog menu. Now, you want to have masthead and left sidebar in the main page but not in sub-pages. To do this, you will need to use a different layout for main page and sub-pages.

The best solution is using a different layout for the main page and sub-page and this feature is not supported by Joomla default. So we added the subpage layout feature where user can assign different layout for sub-pages.

Where layout settings saved?

When you configure layout, the settings will be saved to a .php file, this file is located in templates/gk_blank/layouts/ When I change settings of default layout, the settings will be saved to default.php file.

When you delete the .php files, your layout files will be set to default (the original layout before you took any changes)

Create new layout

There are 2 ways to create new layout.

1. Save As Copy

When you configure layout from back-end, you can clone any layout.

2. Add new layout file

Each layout has its own file. The files are located in: templates/gk_blank/layouts

To create new layout, you should clone a layout file that is most similart with layout you want to create.

Define blocks in layout

Now, open the cloned file and customize. If you want to customize from template setting panel, just open it as once you add new layout file, it will be loaded to layout list in template setting panel.

When open this file, you will see that, there are numbers of blocks that the layout includes. You can add new blocks, or remove the blocks.

To add new blocks to a layout, use the format below.

<?php echo GKTemplate::renderBlock('head') ?>

Create new blocks

To create new block, clonea new block file in: templates/gk_blank/layouts/blocks.

Assign module position to block

Each block has a number of module position assigned to, you can define the assigned module positions for the block using the code format below:

position: header

<jdoc:include type="modules" name="header" style="none" /?>

Add new module position

Step 1: Add module position to block

Open the block file that you want to add new module position to

<jdoc:include type="modules" name="header" style="none" /?>

Step 2: Define the new created module position

When done, you need to define the new created module position in the file: TemplateDetail.xml

          <positions>
               <position>your_module_position_name</position>
          </positions>

Customization

To customize the template you should create the child template from the gk_blank template.

The Joomla 4.1 supported to create the Child Template from the backend.

Prepare things

Step 1: Download and install the gk_blank template.

Step 2: Create Child template from the Backend » Systems » Site templates » gk_blank Details and Files

Step 3: Create the index.php file in your child template folder, and add the following code to the file.

          use Joomla\Plugin\System\Gavick\GKTemplate;
          GKTemplate::render();
     

Template layout system

1. Layout

As a default behavior, the Gavick Framework will load the layout named "default.php" from the "your_template/layouts" folder as the primary layout. You have the flexibility to create additional layouts within the same folder. In the template configuration, you can easily switch to any desired layout.

For instance, if you've created a new layout called "home.php," you can switch to the "home" layout by configuring it in the backend settings.

2. Block

For a complex template, relying solely on the main layout isn't sufficient. To simplify management and promote reusability, consider breaking your layout into smaller components - this is where the block system comes in. You can split your layout into separate files and place them in the "your_template/layouts/blocks" folder. To incorporate them into your main layout or even other block files, you can use this code:

          use Joomla\Plugin\System\Gavick\GKTemplate;
          echo GKTemplate::renderBlock('mainbody');
     

Take note that the "mainbody" block name corresponds to a file path relative to the "blocks" directory. It signifies the display of the content from the "blocks/mainbody.php" file. If the block file is within a subfolder, like "blocks/main/no-sidebar.php," you can display it using this code:

          echo GKTemplate::renderBlock('main/no-sidebar);
     

3. Sublayout

In Joomla, there are instances when you have a menu with a sub-view, like the "article view in menu category." By default, Joomla applies the active menu's template style to that view. If you wish for the subview to have a distinct appearance from the active menu, this can be challenging.

However, within the Gavick Framework, you have the ability to achieve this using the sublayout system.

First, let's examine the configuration in the template:

Gavick now supports to select the menu item for apply sublayout. 2 types of sub view

• Categories » Article
• Category » Article

These layouts will be automatically sourced from the "your_template/layouts/sublayouts/" folder. Within this folder, you can create as many sublayouts as needed.

After configuring the sublayout, you should use the following code to activate the sublayout system within your template:

          <?php if ($sublayout = GKTemplate::getSublayout()): ?>
          <?php echo GKTemplate::renderSublayout($sublayout) ?>
          <?php else : ?>
          <?php echo GKTemplate::renderBlock('mainbody') ?>
          <?php endif ?>
     

Remember to include the namespace:

use Joomla\Plugin\System\Gavick\GKTemplate;

Now the sublayout system is ready for you.

Color preset

The Gavick Framework provides a way to define your CSS variables, configure them, and group them into presets. Moreover, you can create multiple presets according to your requirements. To achieve this, you only need to add some code to your templateDetails.xml. Here's how it works:

          <field name="color_preset" type="GKColorPreset" default_preset="light">
               <preset name="light">
                    <variable name="--gk-primary" group="TPL_GK_BRAND_COLORS">#d05d5d</variable>
                    <variable name="--gk-body-bg" group="TPL_GK_PAGE_COLORS">#ffffff</variable>
               </preset>
               <preset name="dark">
                    <variable name="--gk-primary" group="TPL_GK_BRAND_COLORS">#f9a813</variable>
                    <variable name="--gk-body-bg" group="TPL_GK_PAGE_COLORS">#111111</variable>
               </preset>
          </field>
     

In the above code:

• The field name "color_preset" is mandatory; please do not change it.
• Within the <preset> tag, you define a preset "name" like "light" or "dark," which you can later reference in your template.
• In the <variable> tag, the "name" attribute, such as "--gk-primary," represents your CSS variable used in your CSS. The "group" attribute helps organize your variables into groups, and the value of <variable> tag sets the default value for the respective CSS variable.

After configuring your presets, all the variables will be included in your template's HTML like this:

However, this alone is not sufficient to make presets work in your template. You must also add the following code to your <body> tag:

          <body data-gk-theme="<?php echo GKColorPresetHelper::getActivePreset(); ?>">
     

Don't forget to include namespace

use Joomla\Plugin\System\Gavick\Helper\GKColorPresetHelper;

Add Google Font

With Gavick Framework, you can load google font and define any font family to css variable. Let check the xml

          <field name="body_font" type="GKGoogleFont" default="" variable="--gk-body-font-family" label="Body Font" />
     

In the code above:

• 'name' is your field name, you can use any name
• 'type' must be GKGoogleFont
• 'variable' is the variable that you will use in your css

Once you pick the font at backend config, Gavick Framework will add it to your template html.

Custom font

Once, your fonts are ready for web, you can easily add them to your Joomla website. you just need to follow the simple steps.

#1. add web font folder

Copy your web font folder to: templates/gk_template/media/fonts/

#2: embed font

Now go to your primary stylesheet (in this case templates/gk_template/media/css/custom.css (if it doesn't exist you can create one))

and add the following CSS.

          @font-face {
               font-family: 'sunset_boulevard';
               src: url('../fonts/sunset_boulevard/SunsetBoulevard-Regular.woff2') format('woff2'),
                    url('../fonts/sunset_boulevard/SunsetBoulevard-Regular.woff') format('woff');
               font-weight: normal;
               font-style: normal;
          }
     

if you want to apply it on the body, you can just write the following CSS to your stylesheet.

          body {
               font-family: sunset_boulevard !important;
          }
     

Add custom params for module

The Gavick Framework offers the flexibility to include custom parameters in modules, and you have two options for doing so:

Adding Parameters to All Modules: Create an XML file named "com_modules.module.xml" within the "templates/your_template/form/" directory.

Adding Parameters to Specific Modules: Create an XML file named "module_name.xml" within the "templates/your_template/form/" directory. Replace "module_name with" with the actual name of the module, for example, "mod_custom" or "mod_articles_category".

The XML content can be structured as follows:

          
               <?xml version="1.0" encoding="UTF-8"?>
               <form>
               <fields name="params">
                    <fieldset name="gk_fields" label="GK Fields">
                         <field
                              name="sub_heading"
                              type="text"
                              label="Sub Heading"
                         />
                         <field
                              name="desc"
                              type="textarea"
                              label="Mod Description"
                         />
                    </fieldset>
               </fields>
               </form>
          
     

You can change fields name and fieldset name to anything you want.

Support child template

In Joomla 4.1 or later versions, the Gavick Framework enables you to establish child templates. To enable this feature, you should insert <inheritable>1</inheritable> into your templateDetails.xml. Once done, you can effortlessly create a child template from the Joomla backend.

It's essential to note that Gavick's support for child templates pertains specifically to Joomla layout overrides, Gavick layouts, Gavick blocks, and Gavick sublayouts. This feature does not extend to Joomla media assets. If your intention is to override template JavaScript or CSS, please refer to the following section for guidance on correctly registering JS and CSS.

AddScript, addCss for template

The Gavick Framework in Joomla operates with automatic loading of certain files. By default, it looks for and loads "template.js" and "custom.js" from the "templates/your_template/media/js" folder, as well as "template.css" and "custom.css" from "templates/your_template/media/css" if these files exist.

The framework also follows the same pattern for files named after the layout. For instance, if your layout is named "home", it will attempt to load "home.css" and "home.js" from the respective folders.

To introduce your custom JavaScript or CSS, or even third-party assets like a "carousel," you should first copy these assets to the "templates/your_template/media/" folder. Afterward, you can use the following code to register them:

          use Joomla\Plugin\System\Gavick\GKTemplate;

          GKTemplate::addCss(relative_path_to_media');
          GKTemplate::addScript('relative_path_to_media');
     

In this code, "relative_path_to_media" denotes the path to your JavaScript (or CSS) file in relation to the "templates/your_template/media/" directory. For example, if you have a file located at templates/your_template/media/slider/slider.js", you would use the code like this:

          
               GKTemplate::addScript('slider/slider.js');
          
     

When you use GKTemplate::addScript or GKTemplate::addCss, the Gavick Framework will initially search your child template. If the files are present there, the framework will prioritize loading them.

Some Gavick Framework Elements:

GKMenuElement used to render menu and menu dropdown.

          use Joomla\Plugin\System\Gavick\Element\GKMenuElement;
          echo GKMenuElement::render();
          echo GKMenuElement::renderDropdownButton()

               echo GKOffcanvasElement::render();
          
     

GKPresetElement used to render preset switcher

          
               use Joomla\Plugin\System\Gavick\Element\GKPresetElement;
