Write some text in a paragraph and then using css capitalize the first letter in every word in the paragraph.

Use the capitalize command as in:

p.capitalize {text-transform:capitalize;}

or,
<p class="capitalize">This is some text.</p>

To capitalize the first letter of every word in a paragraph using CSS, you can use the `text-transform` property with the value `capitalize`. Here's an example:

HTML:
```html
<p id="myParagraph">write some text in a paragraph</p>
```

CSS:
```css
#myParagraph {
text-transform: capitalize;
}
```

In this example, we have a paragraph element with the id "myParagraph". By applying the CSS rule `text-transform: capitalize;` to this element, the first letter of every word in the paragraph will be capitalized.

Remember to link the CSS file to your HTML document or include the CSS code within a `<style>` tag in the head section.
