CSS is good for making simple and effective hover effects. JavaScript allows more complex and dynamic behaviors when a user hovers over an element. JavaScript can control exactly what happens when a mouseover event occurs. This includes displaying tooltips, changing content, or triggering animations and transitions that are beyond what CSS can do.
The transition from black to a hue to white is symmetric and is controlled solely by increasing lightness; Decreasing saturation transitions to a shade of gray dependent on the lightness, thus keeping the overall intensity relatively constant; The properties mentioned above have led to the wide use of HSL, in particular, in the CSS3 color model ...

To demonstrate specificity Inheritance Inheritance is a key feature in CSS; it relies on the ancestor-descendant relationship to operate. Inheritance is the mechanism by which properties are applied not only to a specified element but also to its descendants. Inheritance relies on the document tree, which is the hierarchy of XHTML elements in a page based on nesting. Descendant elements may ...
The opposite property of translucency is opacity. Other categories of visual appearance, related to the perception of regular or diffuse reflection and transmission of light, have been organized under the concept of cesia in an order system with three variables, including transparency, translucency and opacity among the involved aspects.
The dissolve mode takes random pixels from both layers. With top layer opacity greater than that of the bottom layer, most pixels are taken from the top layer, while with low opacity most pixels are taken from the bottom layer. No anti-aliasing is used with this blend mode, so the pictures may look grainy and harsh.
Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut-away 3D models of each. Below: two-dimensional plots showing two of a model's three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case the outside surface of each cylinder; horizontal cross-sections (c, g) of constant HSL lightness or HSV value, in this case the slices halfway ...
Below example is for advanced users, showing how we can specify other CSS properties,for example, "font-family", to change the font or "text-decoration" to add lines around the text. Below, on the right side are two userboxes: the top one is displayed without either parameters; and the bottom userbox is displayed by using the below code,
