The difference is the following:

p {} only is a master declaration for your whole page. Definitions here will be inherited by all p tags by default. It is like a default style for p tags.

.name p {} can be used to change the default setting to something else, which will have priority over the default declaration. Note that .name is a class in CSS, so you can reuse it several times, while #name is specific ID in you html code that you want explicitly to modify by css.

For example, if you are building up a forum, you can specify that all p tags by default show in red.
However, each post which is e.g. div, containing some p in it needs to be blue. So it will look like this

<body>
<p>All these will be shown in red</p>
<div class="posts" ><p>My blue content here</p></div>
</body>

But if you want some special formatting do be applied on a specific section of your page only - e.g. header, footer, news, etc..., you should do it like this.

<body>
<p>All these will be shown in red</p>
<div class="posts" ><p>My blue content here</p></div>
<div id="sections_unique_name_here"><p>Only this here will be purple</p></div>
</body>

Note that classes (.name) can appear on a single page multiple times, while id's (#name) can appear on a single page ONLY ONCE!

On a similar note, if you have something like #nav p then it will only do that when it <p> tags are encountered in the <div> section with the ID "nav".

The first one sets the defaukt colour for all <p> elements to red. The second one, overrides this to green, but only for <p> elements in the #nav did.

#nav p h1 wont do anything but #nav p, h1 will. That will override the colour property for both <p> and <h1> tags in the nav section to be red.

Just one thing - <p></p> elements are not allowed to contain h1-h6 elements.
This means you cannot have the following <p><h1>Heading Here</h1>The other text being here</p>

well to me it seems like that its another div with name search-news div. while the first div's name is search-news. it seems like two different divs. and the styles are applied on each one individually they are not connected anyhow.
