In one sentence, describe what the following article is about: CSS be applied in the head of an HTML document, or it can be written as an external CSS document. The head of an HTML document is at the top of the file. It's in between the "<head>" and "</head>" tags. The style section goes in the head of your HTML code, or on a separate style sheet. Use the following tags to create a style section in your HTML or style sheet document. Type <style> to open your style secton. All CSS code goes after this tag. Type </style> to close your style secton. All CSS code goes before this closing tag. p {indent-text: 5em;} This creates tells the browser to create an indent space of 5 spaces when at the proper HTML code. You can adjust the number of spaces by typing a different number after "indent-text:". The "em" unit is equivalent to one space at the specified font size. You can use other units, such as percentage (i.e. "indent-text: 15%;") or measurements (i.e "indent-text: 3mm;"). This goes in the body of your HTML document anywhere you want to indent your text. This will add an indent in your text that matches the specifications in your CSS.
Summary: Open an HTML or CSS document. Create a style section for your CSS. Type the following tag in the style area: Type <p> where you want to add an indent space.

In one sentence, describe what the following article is about: Pharmacies often carry several types of tests that utilize a color-changing strip to assess your cholesterol. They're less expensive than multi-use digital testers, usually costing $20-$50 USD, and are reasonably accurate when used correctly. However, they generally don't break down the different aspects of your cholesterol reading. While often called "single-use" strip kits, don't be confusedmany kits contain multiple testing strips, but each strip can only be used once. You might, for example, find a kit that contains enough single-use strips for 4 individual cholesterol tests. If you're buying a kit online, choose one that's approved by the FDA (in the U.S.) or similar government agency where you live. If you just want to test your cholesterol out of curiosity or only occasionally, this may be the right option for you. If you plan to test your cholesterol more frequentlydue, for example, to your doctor's recommendationa digital readout tester may be a better choice. Wash your hands with soap and water and dry them with a clean towel. Open one of the sealed, sterile packets in your kit that contains a test strip. Do the same with one alcohol swab packet and one packet holding the lancet you'll use to prick your finger. Essentially all test kits now use lancets that are pre-loaded into individual "lancet pens." You'll likely need to pop the cap off of the pen, so check the kit's instructions if you need guidance. Read the product instructions carefully, especially for using the lancet pen. Talk to your pharmacist if you need additional help. The lancets themselves look a bit like large sewing needles, but few if any test kids use lancets that aren't pre-loaded into individual pens. Lancet pens are much easier to use than loose lancets, so always choose a kit that contains pre-loaded pens. Unless your specific product instructions tell you otherwise, do the following: Wipe the alcohol swab over the pad of one of your fingers and let it dry for a few seconds. Press the dispensing end of the pen (it often has a red button at the end) against your finger pad. This causes the lancet to emerge, prick your finger, and retract very quickly. Pull the pen away and set it aside to toss in the trash as soon as you're finished. Do not re-use lancet pens. Throw the pen away after a single use. You'll feel a bit of pain when the lancet pricks your finger, but it will only last for a few seconds. Color-coded strip kits usually take several minutes to produce results. The spot on the testing strip where you wiped your blood sample will slowly change color. Be sure to wait the amount of time directed by the kit's instructions, or your results may not be accurate.Remember to be patient! Assessing a color-coded test strip too early or too late could give you an incorrect result. Since most color-coded strip test kits only test for total cholesterol, your only point of comparison will probably be the recommended total cholesterol range. For the average healthy adult, the ideal range is between 125 to 200 mg/dl. However, your ideal range may be different, based on your particular circumstances. No matter your result, your best option is to share the information with your doctor. "mg/dl" refers to milligrams of cholesterol per deciliter of blood. The higher your mg/dl is, the more susceptible you are to developing blockages in your arteries.
Summary: Choose a color-coded strip kit for a budget-friendly, basic option. Use clean hands to open an alcohol swab, test strip, and lancet. Prick your sterilized finger with the lancet pen to draw blood. Wait the designated amount of time for the test strip to change colors. Compare your result to the recommended total cholesterol range.

In one sentence, describe what the following article is about: Use a ruler to measure the caster's stem. The stem is the metal part that connects the caster to the chair. Also, write down whether or not the stem is threaded or grip. A threaded caster has a screw that screws into the chair, while a grip stem pulls out like a plug from a socket. If your chair has a swivel plate, measure the width of the plate itself. Using a ruler, measure the wheel itself from the front to the back. Most casters come with 22.5in (5.16.4cm) wheels. If you've had difficulty rolling the chair around (say, onto an elevated surface like a rug), consider buying a larger wheel. A twin-wheel caster tends to last longer, since it distributes weight more evenly, but a single-wheel caster is more reliable, since it has less opportunity to fail, having fewer parts. Twin-wheel casters are more often used in office settings, while single-wheel casters are typically found in industrial settings. Casters can be bought from any hardware store or online hardware store. Be sure to take the specifications you've written down with you, as you'll want to be able to compare them and make sure you're buying the right product. If you're shopping for your casters in-person, take one of the old casters with you and ask someone who works there to help you compare.
Summary:
Write down the size of the caster's stem and what kind of stem it is. Measure the wheel from front to back. Decide whether you want a twin-wheel or single-wheel caster. Purchase your new casters from an office supply store.
