1. Universal Selector:- By the help of universal selector, we surpasses the default configuration of browser. It is given by (*) sign.

        * {
            background-color: aqua;
            margin: 0;
            padding: 0;
        }
    </Style>

Here, by universal selector we surpass the default browser configuration.

1. Individual Selector:- This selector selects individual elements of that group. i.e:- paragraph, div, li span etc.

4.           /* * {
5.                background-color: aqua;
6.                margin: 0;
7.                padding: 0;
8.            } */
9.     
10.            span {
11.                color: #383CC1;
12.            }
13.            p {
14.                background-color: #E21717
15.        </Style>

1. Class selector:- class is given by (.) sign. Same “Class” can be provided to different element. Eg:- .red, .white

1. ID selector:- ID is unique it is given by (#) sign. Id is unique to that element it should not be duplicated. Eg:- #red, #white, #bg-red

<div id="red">Lorem, ipsum dolor.</div>
<div class="red">lorem 5</div>

1. Chained selector:- this selector is used to target the specific element.

    <li class="red white">Red</li>
    <li class="red white blue">Blue </li>
    <li class="red white green">Blue black</li>
    </ul>

If we give in CSS (li.red.white) all get selected-

``` li.red.white { background-color: brown; }

But if we give in CSS li.red.white.green then only the target li  is selected


```li.red.white.green {
            background-color: yellowgreen;
         }

1. Combined selector:- selecting combination of 1,2 3... Elements, class, id etc and giving them the same property. This is separated by { , } Like selecting (p, li, div, .class, #id ,ul)

1. Inside an element:- this is concept of selecting different elements. It is separated by a space

```div nav li { background-color: pink; text-align: center;

     }

8. Direct Child:- Selecting the direct child of an element. 
    Like for example:- 

```   div>ul>li{
            background-color: aquamarine;
            text-decoration: underline;
            text-align: center;
            font-weight:bold;

         }

1. Sibling selection:- this is used to select by using “+ or ~” sign. It selects the element just next to its own element. For example:-

 .chemistry + p {
            background-color: brown;
         }
 </Style>


<div class="class">
        <p>organic chemistry has 60% weightage in mains exam </p>
        <ul>
            <li class="chemistry physics">inorganic chemistry</li>
            <p>-- mathematics is a good subject</p>
            <li class="chemistry">organic chemistry</li>
            <li class="chemistry">Physical chemistry</li>
        </ul>
