Topic 1 - HTML Images
Images can improve the design and the appearance of a web page, images are not inserted in the web page rather they are linked to the webpage. The HTML src attribute specifies the URL path to the image, the alt in HTML is the text for the image, this should describe the image or be the title for the image. If the browser can't find the image the page will show the alt text. You can use the style attribute to define the size of the image without tapping into the CSS.
Topic 2 - CSS Color
Colors are specified using predefined color names, or RGB, HEX, HSL, RGBA, HSLA values. You can set the background colors for HTML elements such as header, footer, and body. Along with changing the background color you also can change the color of the text and the color of the border surrounding the text. Color is a very important aspect to designing a website and making it look professional.
