CSS can seem intimidating at first, but with practice and patience, you can become confident in your ability to write CSS code. Remember to understand the basics, essential concepts, and best practices, and don't be afraid to experiment and try new things.

/* Select all paragraphs and apply a font size */ p { font-size: 18px; }

/* Select the element with the ID "logo" and apply a width and height */ #logo { width: 100px; height: 100px; }

Here's an example of CSS code that demonstrates some of the concepts discussed above:

/* Select all elements with the class "header" and apply a background color */ .header { background-color: #333; color: #fff; padding: 20px; }

/* Define a media query for screen sizes below 768px */ @media (max-width: 768px) { /* Apply a different font size for paragraphs on smaller screens */ p { font-size: 16px; } }

CSS is used to style HTML elements. HTML (Hypertext Markup Language) provides the structure of a web page, while CSS controls the layout, appearance, and behavior.

We want to inspire and engage with young people to explore careers in STEM, aviation, and aerospace to support and encourage their future career choices. Aviation and aerospace needs to be ready for the future and we need different talent, ideas and values to make that happen. We are committed to supporting the ambitions and interests of everyone to create opportunities which are inclusive and engaging for all.

STEM (Science, Technology, Engineering and Maths) is the umbrella term used to cover work promoting those subjects in education and to young people. Our work in the area is primarily about promoting the broad range of exciting jobs and careers that are available in aviation along with the skills and knowledge that someone looking to enter the sector could require.

It has been recognised by the aviation community that there will be an anticipated shortage of skilled aviation professionals in the near future.

By promoting awareness of the aviation and aerospace sector, the variety of career pathways you can take and the subjects that help you get there, we aim to inspire young aviators into this industry.
