Magento 2 – Move Category Title Above Products Column

You can retrieve the active category and output it's values

$category = Mage::registry('current_category');
echo $category->getName();
echo $category->getDescr();
// etc

This can be done from any existing PHTML file that is placed there or by adding your own file like so:

local.xml

<catalog_category_layered>
    <reference name="left">
        <block type="core/template" name="top_cat_title" before="-" template="catalog/category/custom_title.phtml"/>
    </reference>
</catalog_category_layered>

Now create a PHTML file in the templates catalog/category directory called custom_title.phtml and add the above PHP code.

This will display the current category data for you

Create the file : app/design/frontend/<package>/<theme>/Magento_Checkout/web/template/onepage.html

And put this content inside :

<!--
/**

 * See COPYING.txt for license details.
 */
-->

<!-- ko foreach: getRegion('progressBar') -->
<!-- ko template: getTemplate() --><!-- /ko -->
<!--/ko-->

<!-- ko foreach: getRegion('authentication') -->
<!-- ko template: getTemplate() --><!-- /ko -->
<!--/ko-->

<!-- ko foreach: getRegion('estimation') -->
<!-- ko template: getTemplate() --><!-- /ko -->
<!--/ko-->

<!-- ko foreach: getRegion('messages') -->
<!-- ko template: getTemplate() --><!-- /ko -->
<!--/ko-->
<div class="opc-wrapper">
    <ol class="opc" id="checkoutSteps">
        <!-- ko foreach: getRegion('steps') -->
        <!-- ko template: getTemplate() --><!-- /ko -->
        <!--/ko-->
    </ol>
</div>

<!-- ko foreach: getRegion('sidebar') -->
<!-- ko template: getTemplate() --><!-- /ko -->
<!--/ko-->

The original file is apps/magento2/vendor/magento/module-checkout/view/frontend/web/template/onepage.html

You might run a magento setup:upgrade to delete pub content in order to force Magento to use your new template file.
