Random question

I dont know if me asking this will make any sense. But what is the difference wen selecting an item in our code, for exemple, selecting the body just like that or selecting the gallery by adding the hashtag or pound symbole in front (#) for what purpouse do we had the hashtag (#) when selecting an item?

here is 2 different exemple:

gallery li {

float: left; width: 45%; margin: 2.5%; background-color: #f5f5f5; }

body { background-color: #fff; color: #999;

}

Tanks!

Hello Marc-Adems, the # symbol is used to select IDs whereas body is simply selecting the body element. Here's a resource for further explanation, and below you could select the ul (unordered list) element, or #gallery, for this demonstration.

        <ul id="gallery"> <!-- This is the gallery ID -->
          <li>
            <a href="img/numbers-01.jpg">
              <img src="img/numbers-01.jpg" alt="">
              <p>Experimentation with color and texture.</p>
            </a>
          </li>

P.S. Hashtags are also used in front of hexadecimal colors.

When you are selecting an element, there are no hashtag's or periods before it. There are lots of elements you can call. Any of these would be valid. There are a lot more.

body { };
input { };
article { };

These are elements, like inputs, articles etc.

When you use a hashtag, you are selecting elements that have an ID of that value.

So #gallery li would select some sort of element, with an ID attribute of gallery. And .gallery li would select some sort element with a class attribute of gallery.

<ul id="gallery">
  <li>List item</li>
</ul>

<div class="gallery">
  <article>
    <p>My article</p>
  </article>
</div>

See how each of those selectors would interact with the above HTML?
