If you are already a user advanced in HTML this post will not be to you helpful, because one is a basic way

In this post we are going to speak on labels HTML or tags HTML, fundamental pillars of all design Web since all website, from smallest to the most advanced makes use of them.

From the start of Internet they become use of them for the construction of the webpages, therefore he is some of the first used programming languages and simply using this language a supersimple€ design can be created €œbut with one it structures understandable.

The form to write these labels is quite easy, is begun writing the symbol €œsmaller than€ <, inside the commando is written who is wanted to use and he is finished with the symbol €œgreater than€ >, and following the type of tag who we want to use they are only closed with the same label that before the first symbol of the closing adds a/bar.

We can use labels HTML to create text paragraphs (<p>), to insert images in our webpage (<img>), to create tables <table>, to construct to lists <ul><li>, to emphasize words or phrases in bold <strong> and a long list of others.

For example, if we want to write a text and to emphasize a word in bold, the codification would be thus:

<p>Hola, this is a text of example with a word emphasized in <strong>negrita</strong></p>

And the result that the navigator interprets, would be this:

Hello, this is a text of example with a word emphasized in bold

We are going to shape another example, in this case I want to create a list of elements.

<ul>

<li>Elemento 1</li>

<li>Elemento 2</li>

<li>Elemento 3</li>

</ul>

As you see, this label has a father <ul></ul> that includes to the children <li></li>, in this case is a list of elements without numeration (Unordered List) and in the navigator veria thus.

  • Element 1
  • Element 2
  • Element 3

If we want to turn this list into a numerical one, we would change tags father <ul></ul> by <ol></ol> (Ordered List), and veria thus.

  1. Element 1
  2. Element 2
  3. Element 3

This is very basic examples but that can serve to you to know the structure this language.

As we shelp more above, language HTML, comes using from the homes of Internet, according to Wikipedia was Tim Berners-Lee, one of the parents of Internet, first using this code there per 1991.

Puncturing here you can see the first e-mail written by him, where towards mention on the use of the labels.

These first labels that were used were coverall to structure texts. <title> made use of the label, that serves to give name to the document and is what appears in the eyelashes of the navigators and labels of format <h1> <h2>, that gave a visual aspect to the titles of the paragraphs. 

Many of these labels are continued using nowadays.

Types of labels HTML

We can divide the labels in different groups according to his function.
