Html block


Html blocks



All the HTML elements can be categorized into two categories 

    (a) Block Level Elements

     (b)Inline Elements.

    Block Elements

    Block elements appear on the screen as if they have a line break before and after them. 

    For example

    , the <p>, <h1>, <h2>, <h3>, <h4>, <h5>, <h6>, <ul>, <ol>, <dl>, 

    <pre>, <hr />, <blockquote>, and <address> elements are all block level elements.

     They all start on their own new line, and anything that follows them appears on its own new line.


    Inline Elements

    Inline elements, on the other hand, can appear within sentences and do not have to appear on a new line of their own. 

    The <b>, <i>, <u>, <em>, <strong>, <sup>, <sub>, <big>, 

    <small>, <li>, <ins>, <del>, <code>, <cite>, <dfn>, <kbd>, and <var> elements are all inline elements.


    Grouping HTML Elements

    There are two important tags which we use very frequently to group various 

    other HTML tags

     (i) <div> tag and

     (ii) <span> tag

    The<div> tag

    This is the very important block level tag which plays a big role in grouping various other 

    HTML tags and applying CSS on group of elements. Even now <div> tag can be used to 

    create webpage layout where we define different parts (Left, Right, Top etc.) of the page 

    using <div> tag. This tag does not provide any visual change on the block but this has more meaning when it is used with CSS.


    Example

    Following is a simple example of <div> tag. We will learn Cascading Style Sheet (CSS)Sheet (CSS) in

    a separate chapter but we used it here to show the usage of <div> tag



    Example

    Following is a simple example of <div> tag. We will learn Cascading Style Sheet (CSS) in a separate chapter but we used it here to show the usag of <div>tag.



    <!DOCTYPE html>

    <html>

    <head>

    <title>HTML div Tag</title>

    <head>

    <body>

    <!-- First group of tags -->

    <div style="color:red">

     <h4>This is first group</h4>

     <p>Following is a list of vegetables</p>

     <ul>

     <li>Beetroot</li>

     <li>Ginger</li>

     <li>Potato</li>

     <li>Radish</li>

     </ul>

    </div>

    <!-- Second group of tags -->

    <div style="color:green">

     <h4>This is second group</h4>

     <p>Following is a list of fruits</p>

     <ul>

     <li>Apple</li>

     <li>Banana</li>

     <li>Mango</li>

     <li>Strawberry</li>

     </ul>

    </div>

    </body>

    </html>



    This will produce the following result:


    This is first group

    Following is a list of vegetables

    • Beetroot
    • Ginger
    • Potato
    • Radish

    This is second group

    Following is a list of fruits

    • Apple
    • Banana
    • Mango
    • Strawberry

    The <span> tag

    The HTML <span> is an inline element and it can be used to group inline-elements in an HTML document.
     This tag also does not provide any visual change on the block but hasmore meaning when it is used with CSS.
    The difference between the <span> tag and the <div> tag is that the <span> tag is used with inline elements whereas the <div> tag is used with block-level elements.

    Example
    Following is a simple example of <span> tag. We will learn Cascading Style Sheet (CSS) in a separate chapter but we used it here to show the usage of <span> tag:

    <!DOCTYPE html>
    <html>
    <head>
    <title>HTML span Tag</title>
    </head>
    <body>
    <p>This is <span style="color:red">red</span> and this is <span style="color:green">green</span></p>
    </body>
    </html>


    This will produce the following result:

    This is red and this is green.
