问题 Goal : Get the button element fixed to the bottom of the main element. I tried positioning it's container with relative positioning so it sticks to the bottom: /* POSITIONING NOT WORKING. I WANT THIS DIV FIXED TO BOTTOM OF PARENT */ .wrapper:nth-child( 4 ) { background-color: #bbb; position: relative; bottom: 0; } This isn't moving the .wrapper div at all. Ideas? @import url( "https://necolas.github.io/normalize.css/latest/normalize.css" ); * { box-sizing: border-box; } main { background

问题 I am reading the "Positioning Techniques" of this article on MDN. It talks about "Absolute positioning elements can be fixed to a position relative to its nearest positioned ancestor element". My understanding of "positioned ancestor" is an ancestor with any position property other than static. But I need expert opinions to verify my thought. 回答1: When referring to positioned ancestor we mean the closest ancestor to the element with a set position value, other than static (which is default).

问题 I am trying to design a table that has a sticky thead and also sticky row headers. So, basically, all th elements must be sticky. I have stumbled across the position: sticky css3 attribute that seems to be a great candidate for the job, even though it's not yet supported in many browsers (which is not an issue to me). However the MDN documentation says: The effect of ‘position: sticky’ on table elements is the same as for ‘position: relative’. Getting this into consideration, I have built a

问题 I have a layout like this: <div class='one'> <div class='two'> <div class='three'>some text</div> </div> </div> Is possible to set relative position for three according to grandfather element ( one ) in CSS? Look this: http://jsfiddle.net/chalist/H48Je/ 回答1: When an element has position: relative and you move it (say left: 20px ) it moves in relation to its natural position in the flow of the page, leaving a gap where it was before (which no other element will grab, as it were). So in a way,

问题 i found interesting feature, but cant find why it happens. So: We have fixed position element, which second under body. First element have styles .firstEl { width:100%; height:200px; background-color:green; } Second element have .fixedEl { position:fixed; right:0; height:100px; width:50px; background-color:red; } Where do you think will be fixed element positioning by top? It`s intresting behavior when js change height of first element and our fixed container change his position too. https:/

问题 I am reviewing the floats property which i learned before,I found a simple issue about floated elements with its own stacking order, the code as: Example 1: .box-1{ background: teal; width:100px; height:100px; float: left; } <div class="box box-1"></div> <p> this is the text for the testing purpose<p> I totally understand the text will wrap around the the box which is right next to the box-1, but when there is no text elements only two div boxes: Example 2: .box { width:100px; height:100px; }

问题 I want a few divs to be positioned in a line next to each other, but also allow them to overlap the previous div. What I'm trying to get is a timeline with divs for events of certain length. The events can overlap each other. My idea was to give each div the same top position, an increasing z-index and an increasing left position (according to the time of the event). Later I would pop individual divs out by mouse-over events to visualise the overlap. What I do is to make it so each div gets
