HTML-CSS: Hamburger Button

HTML-CSS : Exercise-22 with Solution

Using HTML, CSS displays a hamburger menu which transitions to a cross button on hover.

  • Use a .hamburger-menu container div which contains the top, bottom, and middle bars.
  • Set the container to display: flex with flex-flow: column wrap.
  • Add distance between the bars using justify-content: space-between.
  • Use transform: rotate() to rotate the top and bottom bars by 45 degrees and opacity: 0 to fade the middle bar on hover.
  • Use transform-origin: left so that the bars rotate around the left point.

HTML-CSS: Tips of the Day

How to get CSS to select ID that begins with a string ?

[id^=product]

^= indicates "starts with". Conversely, $= indicates "ends with".

The symbols are actually borrowed from Regex syntax, where ^ and $ mean "start of string" and "end of string" respectively.
