Most HTML elements are defined as block level elements or as inline elements.


 Block level elements normally start (and end) with a new line when displayed in a browser.

 Examples: <h1>, <p>, <ul>, <table> 

 Inline elements are normally displayed without starting a new line.

 Examples: <b>, <td>, <a>, <img>

 The HTML <div> Element

 The HTML <div> element is a block level element that can be used as a container for grouping other HTML elements.

  The <div> element has no special meaning. Except that, because it is a block level element, the browser will display a line break before and after it.

 When used together with CSS, the <div> element can be used to set style attributes to large blocks of content.

 Another common use of the <div> element, is for document layout. It replaces the "old way" of defining layout using tables. Using tables is not the correct use of the <table> element. The purpose of the <table> element is to display tabular data.

 The HTML <span> Element

 The HTML <span> element is an inline element that can be used as a container for text.

 The <span> element has no special meaning.

 When used together with CSS, the <span> element can be used to set style attributes to parts of the text.

HTML Layout


Web page layout is very important to make your website look good.Most websites have put their content in multiple columns (formatted like a magazine or newspaper).
          Multiple columns are created by using <div> or <table> elements. CSS are used to position elements, or to create backgrounds or colorful look for the pages.Even though it is possible to create nice layouts with HTML tables, tables were designed for presenting tabular data - NOT as a layout tool!

HTML Layouts - Using <div> Elements

The div element is a block level element used for grouping HTML elements.

The following example uses five div elements to create a multiple column layout, creating the same result as in the previous example:


<!DOCTYPE html>
<html>
<body>

 <div id="container" style="width:500px">

 <div id="header" style="background-color:#00FFFF;">
<h1 style="margin-bottom:0;">Main Title of Web Page</h1></div>

 <div id="menu" style="background-color:#0000FF;height:200px;width:100px;float:left;">
<b>Menu</b><br>
JAVA<br>
HTML<br>
Android</div>

 <div id="content" style="background-color:#EEEEEE;height:200px;width:400px;float:left;">
Content goes here</div>

 <div id="footer" style="background-color:#00FFFF;clear:both;text-align:center;">

The most common HTML lists are ordered and unordered lists:

 An ordered list:

     1. The first list item
    2. The second list item
    3. The third list item
An unordered list:
HTML Unordered Lists

 An unordered list starts with the <ul> tag. Each list item starts with the <li> tag.

 The list items are marked with bullets (typically small black circles).
<ul>
<li>Coffee</li>
<li>Milk</li>
</ul>


  • Coffee
  • Milk
You can add any style as
<ul style="list-style-type:disc">
<ul style="list-style-type:circle">
<ul style="list-style-type:square">

HTML Ordered Lists

An ordered list starts with the <ol> tag. Each list item starts with the <li> tag.

 The list items are marked with numbers.
<ol>
<li>Coffee</li>
<li>Milk</li>
</ol>

Other types are
<ol type="A">
<ol type="a">
<ol type="I">
<ol type="i">

HTML Definition Lists

 A definition list is a list of items, with a description of each item.

 The <dl> tag defines a definition list.

 The <dl> tag is used in conjunction with <dt> (defines the item in the list) and <dd> (describes the item in the list):

 <dl>
<dt>Coffee</dt>
<dd>- black hot drink</dd>
<dt>Milk</dt>
<dd>- white cold drink</dd>
</dl>

Nested List

<ul>
  <li>Coffee</li>
  <li>Tea
    <ul>
    <li>Black tea</li>
    <li>Green tea</li>
    </ul>
  </li>
  <li>Milk</li>
</ul>

Tables are defined with the <table> tag.

 A table is divided into rows (with the <tr> tag), and each row is divided into data cells (with the <td> tag). td stands for "table data," and holds the content of a data cell. A <td> tag can contain text, links, images, lists, forms, other tables, etc.

 Table Example

 <table border="1">
<tr>
<td>row 1, cell 1</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
</tr>
</table>

How the HTML code above looks in a browser:

row 1, cell 1 row 1, cell 2
row 2, cell 1 row 2, cell 2

HTML Tables and the Border Attribute

 If you do not specify a border attribute, the table will be displayed without borders. Sometimes this can be useful, but most of the time, we want the borders to show.

 To display a table with borders, specify the border attribute:

 <table border="1">
<tr>
<td>Row 1, cell 1</td>
<td>Row 1, cell 2</td>
</tr>
</table>

HTML Table Headers


Header information in a table are defined with the <th> tag.

 All major browsers display the text in the <th> element as bold and centered.

<table border="1">
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>row 1, cell 1</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
</tr>
</table>

How the HTML code above looks in your browser:

Header 1 Header 2
row 1, cell 1 row 1, cell 2
row 2, cell 1 row 2, cell 2

Android is the one of the best operating systems for smartphones nowadays. What it is about is how if you have been using your Android all happy go lucky and now feel that it has started to drain out a bit in terms of performance, there are some ways that you can bring it back to its new day glory and have the old efficiency you loved back.
What happens sometimes is that we end up piling up apps, being careless with security, fall behind updates and just pretty much assume that the Android will take care of its self. Unfortunately there is no magic app for maintenance. So here is the manual way to go about it.

Keep your Apps Up to Date

The Android Marketplace is the highlight of having an Android but that doesn’t mean that there aren’t road blocks on the path to glorious app-dom. Whenever apps become out of date there is a high potential of them being infected with viruses or malware that causes damage to your phone as well as results in the slowing down of its processes. So make sure you get the latest updates to ensure that it isn’t an app that’s slowing down your Android.

Install Anti-Malware and Anti-Spyware Tools

The Android market place allows third party apps to be present and hence there is always a chance of a deviant or mal app infiltrating your phone. There may be a cell phone monitoring app or an Android spy app that has found its way onto your device and is causing your phone to slow down and disrupting otherwise smooth functionality by using your processor and internet to collect and transmit personal data. In order to avoid this, as well as boost your Android functionality, install the latest anti-malware and anti-android spy app tools. Find security apps at the play store at this link.

Turn off Unnecessary Programs

Apps when not functioning correctly will indeed put a toll on your Android but there are other things which may be taking your smartphone down too. For instance, background data. Services like Twitter, Facebook, Spying apps and WeatherBug are always downloading data.

 This way when you launch them you get the most updated version of the Newsfeed etc. All you need to do is de-select the Background Data option by going to Settings and then Data Manager. You can also choose to turn off gprs, 2g network in android settings when on the go.

Use Boosting Power Apps

There are a number of amazing apps available on the Android Market designed to help clean and sanctify your phone. Some of them to get you started are Android Assistant and 1Tap Cleaner. These apps perform functions such as History cleaning, cache cleaning, and Startup Manager. These apps also assist in improving battery life so your Android functions better and longer both.

Put a Check on Google Services

Google Services such as Books, Contacts, Currents, etc. all come as part and parcel of Android devices. If you do not use these services then they just end up being extra data your Android continually downloads, putting a toll on other processes and hence the Android’s performance. So simply delete the services you do not need and watch your Android acquire better performance.
