You need to install GenerateBlocks by Tom Usborne.

After you installed the pluging, first we need to write a page title, if you want you can hide the page title in the settings. But writing a page title, gives us a clean permalink.

To make the page title invisible, click on the disable elements>content title.

Now click on the + sign, to add a GenerateBlock.

it is not Gutenberg block, but as I mentioned earlier, we need to add "GenerateBlock" plugin.

It is easily identifyable, as it has blue colour icons, while Gutenberg blocks are not coloured.

The container will look something like this, and you have a lot of options on the right side to set your landing page.

First you can set the layout for your landing page. Select Full width or Contained width, I have selected Full width for all 3 options.

Below that you will find options to edit typography, spacing and colour for your landing page, in which you can choose the background colour, text colour, link colour, hover and border colour.

If you want you can choose a plain colour or there is a setting for choosing gradients. If you want you can add a background image also in this container.

You can adjust colour opacity, by clicking the icon provided.

Now we have created the container for the landing page, you can add other blocks withing this container, by clicking the + sign within the container, and create the whole landing page with this settings. or just add Paragraph block to write a message to your readers.

On the next page, we are going to learn how to add a Lead Generation Form in the container.
