In Photoshop, the easiest way to create a realistic background is to use a combination of the pen tool and the brush tool. First, create a new layer and then use the pen tool to draw a path around the object you want to isolate.
Next, use the brush tool to paint over the object. Finally, use the eraser tool to remove any unwanted parts of the background.
When it comes to styling text in HTML, there are three main tags that you can use: the < p > tag for paragraphs, the < b > tag for bold text, and the < u > tag for underlined text. In most cases, you will want to use the < p > tag to style your text, as it is the most versatile of the three tags. However, if you want to create something that stands out more, like a heading or a subheading, then you may want to use the < b > or < u > tags.
