As I was reviewing my CSS code, I noticed that the h1 tag is defined like this:
h1 { .... }
Unlike everything else in my code, which either has an id "#" or a "." class preceding it. This made me wonder why header tags don't require this. Could it be possible that I made a mistake and they actually do need one?
This indicates that every instance of every occurrence of h1 will adopt the same style. Likewise, you can establish a style for any other element, such as:
p { font-family: Arial; }
This signifies that all p elements will utilize the Arial font.
Keep in mind that it is advisable to only have a single h1 element on a page.

According to information found on this website:
Understanding Type Selectors
A type selector targets specific document language elements by their name. This selector will apply to every occurrence of that element type in the entire document tree.
Therefore, simply specifying the name of a valid element allows for easy selection. This concept can be utilized within more intricate selectors as well.
Header tags are just the beginning. Every component is identified solely by its name. Use '#' to target elements by id and '.' to target elements by class.
The concept here is that the "h1" tag doesn't necessarily require a "class or id". It can certainly have a class or id just like any other tag. It all depends on how you want to utilize it. As previously mentioned, if you wish to apply a universal style to all your h1 tags, then you can omit the class and simply use CSS like so: h1{...}
However, if you desire specific styles for each individual "h1" tag, you can assign a class attribute to distinguish between them as shown in this example:
Assume you have two "h1" tags within your HTML code and you want to apply distinct styles to each one by assigning different colors. You can achieve this as follows:
HTML:
<h1 class="first-header">Hello World1</h1>
<h1 class="second-header">Hello World2</h1>
CSS:
h1.first-header{color:red;}
h1.second-header{color:blue;}
By implementing the above CSS rules, your first h1 tag will be displayed in red text and the second in blue.
