One of my divs is haunted by a phantom top padding, seemingly ignoring my css file












1















I've been working on a very simple navbar for the last two days, just a with a few buttons inside, one of which is supposed to show a dropdown menu. I've set all my paddings with % and for the most part they work, except for the div containing the button that shows the dropdown menu.

As you can see, the .dropdown div (or maybe the button inside) is behaving erratically and instead of having a % padding like I specified everywhere, it sems to have a px padding, only on top, that grows in size as the screen becomes smaller or if zoomed in.



I've sent the code to several peers and friends who are as stumped as I am, especially by the fact that the phantom padding only appears on the top side.

  • Giving a line-height:0 inside the dropdown class in css fixes it for me. Don't ask me why though :)

  • Giving a line-height:0 inside the dropdown class in css fixes it for me. Don't ask me why though :)

A bit tricky to explain but basically it's due to the fact the button is not made float as the a elements and there is the default line-height that define the height of the line box which will be bigger when the font-size get smaller. So the phatom padding is the height of the line box defined by the line-height.



An easy fix it to make the button floating like the links thus it will be a block level element and no more an inline level element.

    That more or less nails it, I think. Another alternative would be to move the font-size:1.2vw from the button to its div container, and set the line-height of the button to inherit, so that the line-height of the div's strut stays the same as that of the buttons.

    That more or less nails it, I think. Another alternative would be to move the font-size:1.2vw from the button to its div container, and set the line-height of the button to inherit, so that the line-height of the div's strut stays the same as that of the buttons.

A bit tricky to explain but basically it's due to the fact the button is not made float as the a elements and there is the default line-height that define the height of the line box which will be bigger when the font-size get smaller. So the phatom padding is the height of the line box defined by the line-height.



An easy fix it to make the button floating like the links thus it will be a block level element and no more an inline level element.

    That more or less nails it, I think. Another alternative would be to move the font-size:1.2vw from the button to its div container, and set the line-height of the button to inherit, so that the line-height of the div's strut stays the same as that of the buttons.
