[MODX] 3. Placeholder +

A Chunk is used in many pages and different page may require different style.

We can use Placeholder to pass in the value.

[[+placeholder_name]]

For exmaple, now we want our home page have blue title and about page have green title.

First, we copy the interior template and create the new template call ' Home template ' and ' about template '.

In Html_header Chunk:we set up the placeholder

      <Headerclass= "group">        <Divclass= "logo">          <H1style= "COLOR: [[+html_header_color]]">[[*longtitle]]</H1>        </Div>

In the Home template:a '? ' followed by ' & ' to pass in K-v pair

[[$html _header?&html_header_color= ' LightBlue ']

In the about template, we don't just like:

[[$html _header]]

What we want are use Defulat value for the placeholder.

Defulat Value:

First:click ' Unlock default Properites ', then create new property. We set color as LightGreen.

Save it.

Then the page should display as we want.
