I would like to have a semi-tranparent animation on my website. Something like a gif, but with opacity that isn't just on or off. Does something like this exist yet? Is it time for someone to create a new image file type? What options do I have for adding animations with transparency to a website? EDIT: The "duplicate question" of this is a question with overlapping answers. It answers this question and more, which is very very nice, but it wasn't intuitive to ask from my perspective, and is similar to comparing the list result of "what dogs have curly hair?" to "describe in detail all the dog types." That is to say, these two questions point to relatively the same place, but come from completely different directions. Like road signs on opposite sides of a city, I don't think a merge is the right decision. EDIT #2: The "duplicate questions" answer doesn't mention that gifs don't have semi-transparency. If you search for the word "transparency" there's zero hits.

marked as duplicate by Zach Saucier, Scott, joojaa, Johannes, Vincent This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question. You can use PNGs or SVGs (which both support alpha transparency) and animate it as a CSS sprite animation. Browse other questions tagged transparency animation or ask your own question.Roof Top Unit and Economizer Animations On most commercial buildings you will find roof top units (RTUs), air handlers that provide heating, cooling, and ventilation to the building’s conditioned spaces. Heating and air conditioning account for over 25 percent of the energy use of commercial buildings, and rooftop units serve 40 percent of commercial floorspace. When the space calls for cooling, a blower in the RTU draws warm air from the space below, through the cooling coil, and then supplies the space below with the cooled air. A similar process occurs to provide heated air.

RTUs also ventilate the space, always supplying some outside air. Notice in the animation below that the outside air damper is no longer fully closed, which allows the RTU fan to bring in a minimum amount of outside air. Notice the addition of pressure relief for the added outside air. A space with people in it requires more ventilation than when it’s unoccupied. An occupancy sensor or a CO2 sensor can respond to changes in ventilation demand, controlling the outside air damper and bringing in more air as necessary. RTU and Economizer Operation An economizer is a control system that takes advantage of outside air conditions to save energy when cooling is called for in the conditioned space. When the outside air temperature is lower than the space temperature, the economizer opens the outside air damper of the RTU and brings in cool air. This saves energy, because otherwise the RTU would cool the inside air mechanically. The following animation shows the standard operation of an RTU with an economizer.
