Magento 2 Tutorial: Theme Customization

In this article, we will discuss about Theme Customization and the best way to customize a Magento 2 theme.

How can you actually customize it?

It is a big question for all of us. Theme customization is not knotty, but we find it difficult to make it efficient and smooth.

Here is the deal:

To perform magento 2 theme customization, you have to take over 2 main stages:  firstly creating a child theme, then starting the customization process.

A. How to make the Child Theme as fast as possible:

Step 1: Go to Content > Design > Themes – Make sure that your child theme (Venustheme Oshop Child) appears in the theme list.

Step 2: Click Stores > Configuration > Design (Magento 2.0.x) or Go to Content > Design > Configuration, choose the Design Theme tab, select the theme (Venustheme Oshop Child) within the dropdown list, click Save Config

And choose child theme:

Step 3: Add the only changed files, not all files into the child theme’s directories.

 Step 4: It’s better to add your own custom css styles into Stores > Configuration > Ves Themesettings > Customization, or edit each sections for general pages, and specify pages.

– Custom Css Code:

– Custom Style Options:

– Or you can add custom css code in the file: app/design/frontend/Venustheme/theme name(oshop_child)/web/css/custom.css

Step 5: We provide the theme customization service with additional cost, please contact us in Request Customization.

B. Detailed process for customization:

1.      How to change the fonts in theme?

As you may now, Venustheme is using google web fonts, so that you can change the google web fonts or use your custom fonts as you want.

1.1.            Change google web fonts:

Ex: Change body font of ves_ishop theme from “Montserrat” to “Roboto”. And custom headings font, product element font to “Verdana”

– Go to admin > Ves Theme Settings > General Settings > Font Settings. Config options “Body fonts” and “Custom fonts”

– Config “Body fonts“:

Input “Font Size” = 13px

“Font Family” = “Google Fonts…”

“Google Font” = “Roboto”

“Character Sets” = “Latin”

Input font weight value (100px, 300px, 400px, 500px,…) as you want, or leave it empty.

– Config “Custom Fonts”:

Click “Add” custom font button, then choose “Custom, Google fonts” = “Roboto”, input “Font Size“, “Font Weight” as you want.

Then input “Font Targets”  – This option is css selector, which html elements will been applied the custom font.

a, Custom font for heading elements:

We use “Font Targets” is: h1,h2,h3,h4,h5,h6,.block .block-title strong

b, Custom font for product element blocks:

We use “Font Targets” is:

.product-block .product-item-inner, .product-block .product-item-details .product-item-name

1.2.            Load and use the custom fonts:

– Upload the font file into the folder “”

– Edit the file “”

2.      How to create new header?

Step1: Created file header1.phtml on this path:

app/design / frontend/ Venustheme/ theme_name / Ves_Themesetting / templates / header /

Step2: You can design and change position block on the header at this file header1.phtml

<?php
$ves = $this->helper('Ves\Themesettings\Helper\Theme');
$sticky = $ves->getHeaderCfg("sticky_settings/sticky");
$sticky_type = $ves->getHeaderCfg("sticky_settings/sticky_type");
$logo = $ves->getHeaderCfg("sticky_settings/logo");
$menu = $ves->getHeaderCfg("sticky_settings/menu");
$search = $ves->getHeaderCfg("sticky_settings/search");
$custom_block = $ves->getHeaderCfg("sticky_settings/custom_block");
$topcart = $ves->getHeaderCfg("sticky_settings/topcart");
$topbar = $ves->getHeaderCfg("sticky_settings/topbar");
$enable_toplinks = $ves->getHeaderCfg("toplinks_settings/enable");
$show_search = $ves->getHeaderCfg("search_settings/search");
$show_topbar = $ves->getHeaderCfg("topbar/show_topbar");

if($sticky_type == 'all'){
 $logo = $menu = $search = $topcart = $toplinks = $topbar= true; 
} 
?>

4.      How to add top link?

In venusthemes, there are 2 ways to add custom top links:

4.1.            In backend:

This function in Venustheme works very well. You can go to backend > Ves Theme settings > Header > Top Links, then add custom link on top-link you want to show:

– With Link option: you can input the link route (ex: contact, the link on frontend will been generated to http://yourdomain.com/contact). Or you can input direct link at here.

The code to call custom links we defined in the file : app\design\frontend\Venustheme\theme_name\Ves_Themesettings\templates\html\link.html

<?php
/**
 * Copyright © 2015 Magento. All rights reserved.
 * See COPYING.txt for license details.
 */
// @codingStandardsIgnoreFile
?>

<?php
$ves = $this->_ves;
$vesData = $this->_vesData;
$html = '';
$id = $block->getIdModifier() ? '-' . $block->getIdModifier() : time();
?>

<div class="header-links" id="header-links<?php echo $id?>">
    <div class="actions dropdown options header-links-options">
        <div class="action toggle switcher-trigger" id="header-links-trigger<?php echo $id?>">
            <strong><?php echo __('My Account') ?> </strong>
        </div>
        <ul class="dropdown header-links-dropdown" data-mage-init='{"dropdownDialog":{
        "appendTo":"#header-links<?php echo $id?> > .options",
        "triggerTarget":"#header-links-trigger<?php echo $id?>",
        "closeOnMouseLeave": false,
        "triggerClass":"active",
        "parentClass":"active",
        "buttons":null}}'>
        <?php
        foreach ($this->getLinks() as $link) {
            $html .= $this->renderLink($link);
        }
        echo $html;
        ?>
        <?php
        //Start call custom top links in ves theme settings
        $custom_links = unserialize($ves->getHeaderCfg('toplinks_settings/custom_links'));
        unset($custom_links['__empty']);
        foreach ($custom_links as $_link) { ?>
        <li class="<?php echo $_link['classes'] ?>" >
            <a href="<?php echo $vesData->filter($_link['link']) ?>" target="<?php echo $_link['target'] ?>"><?php echo $_link['title'] ?></a>
        </li>
        <?php } ?>
    </ul>
</div>
</div>

4.2.            By layout xml:

For example:

– To create a link to a custom cms page “Contact Us” with route “contact-us”, you need to create a CMS page for example you create an “Contact Us” page with identifier as “contact-us”
The link access to contact page on frontend: http://domain.com/contact-us

– To add magento 2 top links, you need to add following code in default.xml of your theme
Add code in body tag of a file *.xml. For example:

app/design/frontend/Magento/YOUR_THEME/Magento_Theme/layout/default.xml

<referenceBlock name="header.links">
 <block class="Magento\Framework\View\Element\Html\Link" name="contact-link">
  <arguments>
   <argument name="label" xsi:type="string" translate="true">Contact Us</argument>
   <argument name="path" xsi:type="string" translate="true">contact-us</argument>
  </arguments>
 </block>
</referenceBlock>

The previous code will be redirected to “Magento\Framework\View\Element\Html\Link” class and tranfers label = Contact Us and path = contact-us (http://domain.com/contact-us)
After that, Check the PHP Magento\Framework\View\Element\Html\Link.php file, there is one link shown on frontend:

protected function _toHtml()
{
    if (false != $this->getTemplate()) {
        return parent::_toHtml();
    }
 return '<li><a ' . $this->getLinkAttributes() . ' >' . $this->escapeHtml($this->getLabel()) . '</a></li>';
}

                </arguments>
            </block>
        </referenceContainer>

7.      How to change page layout of category page (1 column, 2 columns left, 2 columns right, or 3 columns)?

– The type of page layout used for a certain page is defined in the page configuration file, in the layout attribute of the root <page> node. Hence, if you want to change page layout of category page, you should customize “page configuration” file.

Example: Change the layout of Category page from default “1-column” to “2-column with left bar“. To do this, edit the file:

app/design/frontend/Venustheme/<theme>/Magento_Catalog/layout/catalog_category_view.xml

<page layout="2columns-left" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
...
</page>

8.      How to show product attribute value as brand name?

In this section, we will demonstrate by the following example.

We have a product attribute with code: sku we want to show brand information under product title

– Edit the file “app/design/frontend/Venustheme/<theme>/Magento_Catalog/templates/product/list.phtml”

– Find the line code:

 <?php if($show_name){ ?>
                    <strong class="product name product-item-name">
                        <a class="product-item-link"
                        href="<?php /* @escapeNotVerified */ echo $_product->getProductUrl() ?>">
                        <?php /* @escapeNotVerified */ echo $_helper->productAttribute($_product, $_product->getName(), 'name'); ?>
                    </a>
                </strong>
                <?php } ?>
