Implement transition effects for image replacement using pure Javascript

On a website I created, I have a number of accordions, each with an image on top. When you open the accordion, there is a description inside and the image changes to another. Then when you close the accordion, the image switches back to the first image. The problem is that I want this image change to have a smooth transition, with a fade effect, whereas now it's just a sudden change. what should I do? Let's say the accordion button has the id "button"; the label containing the first image (which will be changed to the second image) has the id "firstimage". This is JavaS

Gradient effect of CSS display properties

I'm currently designing a CSS "super dropdown" - basically a regular pure CSS dropdown, but with different types of content in it. Currently, it seems that CSS3 transition effects do not apply to the "display" property, that is, there is no way to transition from display:none to display:block (or any combination). In the example above, is there a way to make the second level menu "fade in" when someone hovers over the top menu item? I know it's possible to use a transition effect on the visibility: attribute, but I can't figure out how to use it effectively

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records. I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
