<dt> What is Mineral</dt>
<dd>Minerals are substances that are formed naturally in the Earth. There are around 4000 minerals on the earth surface. Minerals are usually solid and inorganic with a crystal structure and form naturally by geological processes. The study of minerals is called mineralogy.
</dd>
<dt> Metallic Minerals </dt>
<dd>Metallic minerals are composed of metals in their original form and possess a very crystalline atomic arrangement. Metallic minerals are composed of ferrous minerals and non-ferrous minerals.
</dd>
<dt>Classification of Minerals </dt>
<dd> Minerals are classified in terms of the arrangement of their atomic number as well as valency of electrons. While elaborating upon minerals and energy resources, let take a look at the classification of Minerals
</dd>
<dt> Energy Resources </dt>
<dd> Energy resources are all forms of fuel that we use in modern times petroleum, LPG, and CNG. Similar to the classification of minerals, Energy resources are also divided into following types.
</dd>
<dt> Conventional Resources </dt>
<dd> Also called non-renewable energy, the conventional energy resources are those that cannot be reused once they cease to exist on the earth surface. These include coal, petroleum, natural gas, and electricity.
</dd>
<dt> Geothermal Energy</dt>
<dd> When heat and electricity are generated by using thermal energy from the inside of the earth, it is known as Geo-Thermal Energy. In India, geothermal energy is wielded from Parvati Valley near Manikarn, Himachal Pradesh, and Puga Valley, Ladakh.

About HTML

HTML(Hyper Text Markup language) is the standard markup language for Web pages, was created by Berners-Lee in the year 1991. Almost every web page over internet might be using HTML.

Syntax help

Fundamentals

  • Any HTML document must start with document declaration <!DOCTYPE html>
  • HTML documents begin with <html> and ends with </html>
  • Headings are defined with <h1> to <h6> where <h1> is the highest important heading and <h6> is the least important sub-heading.
  • Paragrahs are defined in <p>..</p> tag.
  • Links are defined in <a> tag.

    Example:

    <a href="https://onecompiler.com/html">HTML online compiler</a>
  • Images are defined in <img> tag, where src attribute consists of image name.
  • Buttons are defined in <button>..</button> tag
  • Lists are defined in <ul> for unordered/bullet list and <ol> for ordered/number list, and the list items are defined in <li>.

HTML Elements and Attributes

  • HTML element is everything present from start tag to end tag.
  • The text present between start and end tag is called HTML element content.
  • Anything can be a tagname but it's preferred to put the meaningful title to the content present as tag name.
  • Do not forget the end tag.
  • Elements with no content are called empty elements.
  • Elements can have attributes which provides additional information about the element.
  • In the below example, href is an attribute and a is the tag name.

    Example:

    <a href="https://onecompiler.com/html">HTML online compiler</a>

CSS
