To explicitly associate a element with an element, you first need to add the id attribute to the element. Next, you add the for attribute to the element, where the value of for is the same as the id in the element.

Placing heading elements within a interferes with many kinds of assistive technology, because headings are commonly used as a navigation aid. If the label's text needs to be adjusted visually, use CSS classes applied to the element instead.

An element with a type="button" declaration and a valid value attribute does not need a label associated with it. Doing so may actually interfere with how assistive technology parses the button input. The same applies for the element.

An element with a type=\"button\" declaration and a valid value attribute does not need a label associated with it. Doing so may actually interfere with how assistive technology parses the button input. The same applies for the element.

Labels are key/value pairs that are attached toobjects such as Pods.Labels are intended to be used to specify identifying attributes of objectsthat are meaningful and relevant to users, but do not directly imply semanticsto the core system. Labels can be used to organize and to select subsets ofobjects. Labels can be attached to objects at creation time and subsequentlyadded and modified at any time. Each object can have a set of key/value labelsdefined. Each Key must be unique for a given object.

Service deployments and batch processing pipelines are often multi-dimensional entities(e.g., multiple partitions or deployments, multiple release tracks, multiple tiers,multiple micro-services per tier). Management often requires cross-cutting operations,which breaks encapsulation of strictly hierarchical representations, especially rigidhierarchies determined by the infrastructure rather than by users.

If the prefix is omitted, the label Key is presumed to be private to the user.Automated system components (e.g. kube-scheduler, kube-controller-manager,kube-apiserver, kubectl, or other third-party automation) which add labelsto end-user objects must specify a prefix.

The API currently supports two types of selectors: equality-based and set-based.A label selector can be made of multiple requirements which are comma-separated.In the case of multiple requirements, all must be satisfied so the comma separatoracts as a logical AND (&&) operator.

Equality- or inequality-based requirements allow filtering by label keys and values.Matching objects must satisfy all of the specified label constraints, though they mayhave additional labels as well. Three kinds of operators are admitted =,==,!=.The first two represent equality (and are synonyms), while the latter represents inequality.For example:

The former selects all resources with key equal to environment and value equal to production.The latter selects all resources with key equal to tier and value distinct from frontend,and all resources with no labels with the tier key. One could filter for resources in productionexcluding frontend using the comma operator: environment=production,tier!=frontend

Similarly the comma separator acts as an AND operator. So filtering resourceswith a partition key (no matter the value) and with environment differentthan qa can be achieved using partition,environment notin (qa).The set-based label selector is a general form of equality sinceenvironment=production is equivalent to environment in (production);similarly for != and notin.

LIST and WATCH operations may specify label selectors to filter the sets of objectsreturned using a query parameter. Both requirements are permitted(presented here as they would appear in a URL query string):

matchLabels is a map of key,value pairs. A single key,value in thematchLabels map is equivalent to an element of matchExpressions, whose keyfield is "key", the operator is "In", and the values array contains only "value".matchExpressions is a list of pod selector requirements. Valid operators includeIn, NotIn, Exists, and DoesNotExist. The values set must be non-empty in the case ofIn and NotIn. All of the requirements, from both matchLabels and matchExpressionsare ANDed together -- they must all be satisfied in order to match.

For instance, different applications would use different values for the app label, but amulti-tier application, such as the guestbook example,would additionally need to distinguish each tier. The frontend could carry the following labels:

Sometimes you may want to relabel existing pods and other resources before creatingnew resources. This can be done with kubectl label.For example, if you want to label all your NGINX Pods as frontend tier, run:

The information in the main or top section (see #1-4) of the sample nutrition label (below) can vary with each food and beverage product; it contains product-specific information (serving size, calories, and nutrient information). The bottom section contains a footnote that explains the % Daily Value and gives the number of calories used for general nutrition advice.

In the Nutrition Facts label below we have colored certain sections to help you focus on those areas that will be explained in detail. Note that these colored sections are not on the actual food labels of products you purchase.

When looking at the Nutrition Facts label, first take a look at the number of servings in the package (servings per container) and the serving size. Serving sizes are standardized to make it easier to compare similar foods; they are provided in familiar units, such as cups or pieces, followed by the metric amount, e.g., the number of grams (g). The serving size reflects the amount that people typically eat or drink. It is not a recommendation of how much you should eat or drink.

Calories provide a measure of how much energy you get from a serving of this food. In the example, there are 280 calories in one serving of lasagna. What if you ate the entire package? Then, you would consume 4 servings, or 1,120 calories.

To achieve or maintain a healthy body weight, balance the number of calories you eat and drink with the number of calories your body uses. 2,000 calories a day is used as a general guide for nutrition advice. Your calorie needs may be higher or lower and vary depending on your age, sex, height, weight, and physical activity level. Learn your estimated calorie needs at -plan.

Total Sugars on the Nutrition Facts label includes sugars naturally present in many nutritious foods and beverages, such as sugar in milk and fruit as well as any added sugars that may be present in the product. No Daily Reference Value has been established for total sugars because no recommendation has been made for the total amount to eat in a day.

Added Sugars on the Nutrition Facts label include sugars that are added during the processing of foods (such as sucrose or dextrose), foods packaged as sweeteners (such as table sugar), sugars from syrups and honey, and sugars from concentrated fruit or vegetable juices. Diets high in calories from added sugars can make it difficult to meet daily recommended levels of important nutrients while staying within calorie limits.

Dietary fiber, vitamin D, calcium, iron and potassium are nutrients on the label that Americans generally do not get the recommended amount of. They are identified as nutrients to get more of. Eating a diet high in dietary fiber can increase the frequency of bowel movements, lower blood glucose and cholesterol levels, and reduce calorie intake. Diets higher in vitamin D, calcium, iron, and potassium can reduce the risk of developing osteoporosis, anemia, and high blood pressure.

The % Daily Value (%DV) is the percentage of the Daily Value for each nutrient in a serving of the food. The Daily Values are reference amounts (expressed in grams, milligrams, or micrograms) of nutrients to consume or not to exceed each day.

Do you need to know how to calculate percentages to use the %DV? No, because the label (the %DV) does the math for you! It helps you interpret the nutrient numbers (grams, milligrams, or micrograms) by putting them all on the same scale for the day (0-100%DV). The %DV column doesn't add up vertically to 100%. Instead, the %DV is the percentage of the Daily Value for each nutrient in a serving of the food. It can tell you if a serving of food is high or low in a nutrient and whether a serving of the food contributes a lot, or a little, to your daily diet for each nutrient.

Compare Foods: Use %DV to compare food products (remember to make sure the serving size is the same) and more often choose products that are higher in nutrients you want to get more of and lower in nutrients you want to get less of.

Dietary Trade-Offs: You can use the %DV to help you make dietary trade-offs with other foods throughout the day. You don't have to give up a favorite food to eat a healthy diet. When a food you like is high in saturated fat, balance it with foods that are low in saturated fat at other times of the day. Also, pay attention to how much you eat during the entire day, so that the total amount of saturated fat, as well as other nutrients you want to limit, stays below 100%DV.
