As tass_co already said, whenever are you posting codes, you should include them into <code> tags. This can be done by the </> button in the menu of this forum. If you do this, you can't color parts of codes, as you did with plain text. I added the needed tags, but didn't remove the [color] tags, but as you can see, it is not applied in codes.
However, none of the posted options are not valid in the form you've used them. They all are options which should not be used in the code of your skin, but into the [Skin] section of the Rainmeter.ini. Rainmeter.ini is the file which stores all skins-related settings. It can be accessed by a right-click to the Rainmeter icon in the Notification Area, then a click to Edit settings. You get opening the Rainmeter.ini file into the default text editor. Here you should identify the name of your config. All three options (HideOnMouseOver, FadeDuration and AlphaValue) should be added in the appropriate secztion of this file, with the following mentions: Besides this, question is what exactly would you want to achieve, because same way as tass_co, me didn't really understood your intention either.
