###[A] Code only answer While this code snippet may solve the question, including an explanation really helps to improve the quality of your post. Remember that you are answering the question for readers in the future, and those people might not know the reasons for your code suggestion. Please also try not to crowd your code with explanatory comments, this reduces the readability of both the code and the explanations!
###[A] Question as answer This post isn't an actual attempt at answering the question. Please note $SITENAME$ doesn't work like a discussion forum, it is a Q&A site where every post is either a question or an answer to a question. Posts can also have comments - small sentences like this one - that can be used to critique or request clarification from an author. This should be either a comment or a new question.
###[A] Me too! Please don't add "Me too" as an answer. It doesn't actually provide an answer to the question. If you have a different but related question, then ask it (reference this one if it will help provide context). If you're interested in this specific question, you can show your interest by upvoting it or leaving a comment once you have enough reputation.
###[A] Thanks! Please don't add "thanks" as answers. They don't actually provide an answer to the question, and can be perceived as noise by its future visitors. Once you earn enough reputation, you will gain privileges to upvote answers you like. This way future visitors of the question will see a higher vote count on that answer, and the answerer will also be rewarded with reputation points. See Why is voting important.
###[A] Comment as answer This does not provide an answer to the question. To critique or request clarification from an author, leave a comment below their post. If you earn sufficient reputation you will be able to comment on any post.
###[A] Many formatting issues
Take a moment to read through the editing help in the help center. Formatting on
###[A] Duplicate link only
Please don't post link only answers to other
###[A] Link only to other SE Please don't post link only answers to other Stack Exchange questions. Instead, include the essential portions of the answer here, and tailor the answer to this specific question.
###[A] Link only answer A link to a potential solution is always welcome, but please add context around the link so your fellow users will have some idea what it is and why it’s there. Always quote the most relevant part of an important link, in case the target site is unreachable or goes permanently offline. Take into account that being barely more than a link to an external site is a possible reason as to Why and how are some answers deleted?.
###[A] Answering off-topic / bad question Please don't post answers on obviously off topic / bad questions! See: Should one advise on off topic questions?
###[A] Code as image Please don't post your code as an image.
###[A] Identical answers Please don't post identical answers to multiple questions. Post one good answer, then vote/flag to close the other questions as duplicates. If the question is not a duplicate, tailor your answers to the question.
###[A] OP using an answer for further information Please use the Post answer button only for actual answers. You should [edit] your original question to add additional information.
###[A] OP adding a new question as an answer If you have another question, please ask it by clicking the Ask Question button.
###[A] Non English answer Please write your answer in English, since $SITENAME$ is an English site.
###[A] Self Promotion Just linking to your own library or tutorial is not a good answer. Linking to it, explaining why it solves the problem, providing code on how to do so and disclaiming that you wrote it makes for a better answer. See: What signifies “Good” self promotion?
###[A] Language, please
I know you're excited, but please try to keep your language under control. Think of
