Q45. _ moves an element completely out of the page's normal layout flow like it is sitting on its own separate layer. From there, you can fix it in a position relative to the edges of the page's <html> element (or its nearest positioned ancestor element).
- Sticky positioning
- Absolute positioning
- Relative positioning
- Fixed positioning
position: absolute;
An element with position: absolute; is positioned relative to the nearest positioned ancestor (instead of positioned relative to the viewport, like fixed). However; if an absolute positioned element has no positioned ancestors, it uses the document body, and moves along with page scrolling.
Q46. You have created a box that has a height set with CSS. Which line of CSS would add scroll bars if the content is taller than the box, but leave no visible scroll bars if the content fits into the box?

- .box { overflow: auto; }
- .box { overflow: none; }

Q48. The image below has float: left applied. Text wraps the float on the right and bottom. How would you force the second paragraph to start underneath the float, leaving a gap after the preceding paragraph?
- Apply
float: leftto the second paragraph. - Apply
clear: rightto the floated item. - Apply
clear: leftto the second paragraph. - Apply
clear: leftto the floated item.
clear: left;
When we use the float property, and we want the next element below (not on the right or left), we will have to use the clear property. When clearing floats, you should match the clear to the float: If an element is floated to the left, then you should clear to the left. Your floated element will continue to float, but the cleared element will appear below it on the web page.
Q49. You want to create striped table rows using CSS without adding a class to any element. Which CSS would correctly apply the background color to every odd row in your table?
-
tr:nth-child(2) { background-color: #ccc; } -
tr:nth-child(2n+1) { background-color: #ccc; } -
tr:nth-child(2+1) { background-color: #ccc; } -
tr:nth-child(2n) { background-color: #ccc; }
