Double size my icons! Options

[N1c0lat0]

Hi All.

This is my site: http://native-speaker.biz/ I’m looking for a way to double-size the icons on my home page. There are six of them in total. You can see them here:

The Wordpress theme used for the site is Alchem. I edit the content in the section with the icons here, in Wordpress: Appearance > Customize > Homepage > Section: Service.

If I inspect the source code for one of the icons shown above, I see this:

CODE

<img class="feature-box-icon " src="http://native-speaker.biz/wp-content/uploads/2017/08/Optimise_icon_compact-1.png" alt="" scale="0" style="visibility: visible;">

So, I reckon it’s possible to adjust the scale using this element: scale=”0″. Also, I see that this probably means that I must switch the Wordpress content model from 'default' to 'custom content'. But, once that's done, I will need to extract the source for the existing content I have in that section and I don't know how to do that.

So, to the specific questions:

1. How do I extract the source code for the content in the Home Page > Features section?
2. How should I adjust this source code to double-size the six icons?
3. Should the adjusted code be placed in the custom content field at the bottom of the Wordpress editing interface (Appearance > Customize > Homepage > Section: Service) - or somewhere else? (Guidance note pasted from the interface: "Custom Section Content - This would display instead of fixed layout once Content Modal is set as Custom. HTML Code and Shortcode are both allowed.")

Many thanks for any help you can provide!
