The "class" in html and css

Question

So in The HTML: <h1>.......</h1> <p class="example">......</p>. The CSS: h1 {.........} p.example{....}
so why h1 has no "class" and p has "class"? i don't know where i missed that, please help, Thanks!

Answer 1

Classes are a way to categorize html elements. You can then apply a style to all the elements sharing the same class at once for example.

Answer 2

<style> is for when you want to insert css in an html document. Prefer using a separate css file if possible.

Answer 3

h1 can also have class attribute

<style>
.d{color:blue;}
</style><h1 class=d>This is a Blue Heading</h1>

Answer 4

thanks for the answer. btw ManojKumar, for that code is the style tag necessary or can do without it just : .d{color:blue;} ?

Answer 5
