About Leslie

Theme has three layouts you can use to make three types of page layouts. Single posts pages and regular blog page content are displayed with content on the right and a sidebar and a navigation bar each to the left. Individual Pages that you create are displayed with content in the middle and sidebar/menu on each side of content. There is a third layout that you can have by using the template named "Portfolio Page" to show custom posts on the far right, tiled vertically kind of like a gallery. These custom posts have their own editor and the plugin for it is installable from within the theme. Options to add social media links with icons; change link colors, background and header image. Theme uses a responsive framework but is not fully optimized for all screens. As of v. 1.3 there is option to change footer text. Demo at https://leadspilot.com/leslie/

Why use a child theme for Leslie?

Every time Leslie ships an update, any direct edits you made to its files are overwritten. A child theme isolates your changes — custom CSS, template overrides, additional functions — so the parent can update freely while your customizations stay intact.

  • Survive Leslie updates without losing your edits.
  • Override any Leslie template file by copying it into the child.
  • Add custom hooks, shortcodes, or enqueue your own scripts.
  • Roll back to the parent at any time by deactivating the child.

Frequently asked questions

What is a Leslie child theme? +

A child theme is a separate WordPress theme that inherits all functionality, design, and templates from Leslie (its parent). You make your customizations in the child so they survive updates to the parent theme.

Do I need to know code to use this generator? +

No. The generator creates a complete, valid Leslie child theme with style.css, functions.php, screenshot.png, and README.txt. You can customize via the form fields, and if you want to add custom CSS or PHP later you can edit the files directly.

Will the child theme break when Leslie updates? +

That's exactly what a child theme is designed to prevent. Leslie can be updated freely without losing your customizations, because they live in the child theme files.

Is this generator really free? +

Yes. There is no signup, no payment, and no limit on how many Leslie child themes you can generate. The zip is built on demand and downloaded directly to you.
