Besides using special non-proteinacous fluorescent dyes to label cellular compartments it is also possible to stain the area of interest with the help of proteins with preferences for distinct locations in the cell. These proteins can be linked to a fluorescent dye and visualized in the fluorescent microscope.
The HTML <body> tag is used for declaring the main content section of the HTML document. The <body> tag is placed after the document's head (i.e. between the </head> and the </html> tags). The basic tag is written like this <body></body>, with the document's content inserted between the opening and closing tags. On any normal-sized HTML document, you'll usually see the opening tag (<body>) near the top of the document and the closing tag (</body>) near the bottom.
Elements can also have content, including other elements and text. Many HTML elements represent semantics, or meaning. For example, the title element represents the title of the document. In the HTML syntax, most elements are written with a start tag and an end tag, with the content in between. An HTML tag is composed of the name of the element, surrounded by angle brackets. An end tag also has a slash after the opening angle bracket, to distinguish it from the start tag.
