Today we discuss how in Magento 2 create simple theme? Creating a simple theme or custom theme is consisting on four easy step in magento2. First you have to create your SpaceName in my case it is QaisarSatti. Create folder in app/design/frontend/QaisarSatti. Now add the theme name after app/design/frontend/QaisarSatti/theme.

First Step:

Create the composer.json file for theme.

app/design/frontend/QaisarSatti/theme/composer.json

{
"name": "magento/theme-frontend-blank",
"description": "My First Theme",
"require": {
"php": "~5.5.0|~5.6.0|~7.0.0",
"magento/theme-frontend-blank": "100.0.*",
"magento/framework": "100.0.*"
},
"type": "magento2-theme",
"version": "100.0.1",
"license": [
"OSL-3.0",
"AFL-3.0"
],
"autoload": {
"files": [
"registration.php"
]
}
}

Second Step:

In this step we will register our theme.

app/design/frontend/QaisarSatti/theme/registration.php

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

\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::THEME,
    'frontend/QaisarSatti/theme',
    __DIR__
);

Third Step:
Create the theme.xml file. Here you will define the parent theme for your theme so in my case the magento blank theme.

app/design/frontend/QaisarSatti/theme/theme.xml

<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
     <title>My First Theme</title> <!-- your theme's name -->
     <parent>Magento/blank</parent> <!-- the parent theme, in case your theme inherits from an existing theme -->
     <media>
         <preview_image>media/preview.jpg</preview_image> <!-- the path to your theme's preview image -->
     </media>
 </theme>
