Example:

SELECT employee_id, first_name, job_title
FROM employees
WHERE job_title = 'Manager';

Let's break down the SQL code:

SELECT: This keyword indicates that we want to retrieve data from the table.
employee_id, first_name, job_title: These are the columns we want to retrieve data from. 
We specified three columns: "employee_id," "first_name," and "job_title."
FROM: This keyword indicates the table from which we want to retrieve data. 
In this case, we want data from the "employees" table.
WHERE: This optional keyword is used for filtering the rows. 
We can specify a condition to retrieve only those rows that satisfy the given condition.
job_title = 'Manager': This is the condition specified in the WHERE clause. 
It means we only want to retrieve rows where the "job_title" column has the value "Manager."

When you run this SQL code as a query in Microsoft Access, it will return a result set containing the "employee_id," "first_name," and "job_title" columns for all employees who have the job title "Manager." The result will be displayed in the Datasheet View, showing only the relevant information based on the specified condition.

Let's walk through an example of the SELECT statement step by step. 
Suppose we have a table named "employees" in the Microsoft Access database with the following columns: 
"employee_id," "first_name," "last_name," "job_title," and "salary."

Step 1: Connect to the Database
First, you need to open Microsoft Access and open the database that contains the "employees" table.

Step 2: Launch the Query Design View
To execute a SELECT statement, you can create a query in Access using the Query Design View.

    Click on the "Create" tab in the top menu.
    Click on "Query Design" in the "Queries" group.

Step 3: Add the Table to the Query Design View
In the Query Design View, you will see the "Show Table" dialog. 
Add the "employees" table to the query design by double-clicking on it or selecting it and clicking the "Add" button.

Step 4: Select Columns to Retrieve Data
You will see the "employees" table added to the Query Design View with all its columns. 
To specify which columns you want to retrieve, drag and drop them from the table grid to the query design area.

Let's say we want to retrieve the "employee_id," "first_name," and "job_title" columns:

Step 5: Specify the Criteria (Optional)
If you want to filter the results based on specific conditions, you can use the "Criteria" row in the query design grid. 
For example, if you only want to retrieve employees with a certain job title (e.g., "Manager"), you can add the condition in the "Criteria" row for the "job_title" column:

Step 6: Run the Query
Once you have defined the SELECT statement in the Query Design View, click the "Run" button (it looks like a red exclamation mark) in the top menu to execute the query.

Step 7: View the Results
After running the query, you will see the results displayed in the Datasheet View. 
The Datasheet View will show the selected columns from the "employees" table, filtered based on any conditions you specified.

That's it! You have successfully executed a SELECT statement in Microsoft Access to retrieve specific columns from the "employees" table, and optionally filtered the results based on certain criteria.

Remember, you can save the query for future use or modify it as needed. 
SELECT statements are the foundation of data retrieval in SQL, allowing you to view specific information from the database tables.

The a element in HTML is used to create hyperlinks, allowing you to link to other web pages, resources, files, or specific sections within a page.

Example: 

1. Semantic elements:

HTML5 introduces many new semantic elements that help describe the structure of the content better, making it easier for search engines and screen readers to understand the page's purpose. Some key semantic elements include header, nav, main, article, section, footer, aside, etc.

2. Multimedia:

HTML5 provides built-in support for audio and video without the need for plugins like Flash. 
The audio and video elements allow embedding media directly into the page.

Example:

HTML5 (Hypertext Markup Language 5) is the latest version of the standard markup language used for creating and structuring content on the web. 
It comes with several new features and improvements over its predecessors.

Place your hand on your forehead.
Push your head forward against your hand while resisting with your hand.
Hold the tension for 5-10 seconds, then relax.
Repeat the isometric push in all directions: forward, backward (placing hand on the back of your head), and sideways (placing hand against the side of your head).
Repeat each direction 5-10 times.

Sit or stand with your back straight.
Slowly lift both shoulders towards your ears.
Hold for 5-10 seconds, then relax.
Repeat the shoulder shrug 10-15 times.

Sit or stand with your back straight.
Tuck your chin in towards your neck without tilting your head up or down.
Hold the position for 5-10 seconds.
Relax and repeat 5-10 times.

Sit or stand with your back straight.
Slowly tilt your head forward, bringing your chin toward your chest (flexion).
Hold the stretch for 15-30 seconds.
Gently lift your head and look up towards the ceiling (extension).
Hold for 15-30 seconds.
Repeat the flexion and extension stretches 2-3 times each.

Sit or stand with your back straight.
Slowly turn your head to one side, looking over your shoulder.
Hold the stretch for 15-30 seconds.
Return to the starting position and repeat on the other side.
Perform this stretch 2-3 times on each side.
