How is position:relative different in effect from using margin spacing to “move” the element?

3 Likes

By offsetting from the default static position of the div using the top, left etc properties, does that not make the position command superfluous?

top, left etc don’t work on static elements, nothing happens.

Besides relative and static, there also other possible values for position (fixed for example)

lets do an example:

https://jsbin.com/dukidawico/edit?html,css,output

if you uncomment (ctrl + /) the css, you will see that both divs move down

this is because margin is applied first, then the elements are “rendered”, causing both to move down.

if we use move (again, uncomment the css line):

https://jsbin.com/dokarohiye/edit?html,css,output

the elements are “rendered” first, and then the #first element is pushed down, causing overlap, because the second element doesn’t move.

Hello All,
Just want to know in above exercise we have 5 question classes(.question) and we gave them

postion:relative;

and offset

top:40px;

so my question is why this offset top 40px applied to only first question class why it have no effect on other question classes?

Are you sure? Have you tested this hypothesis? Go ahead, and only apply the top: 40px to the first question. (use an id selector or nth, whichever you prefer)

Yes Sir I tested this,
My style.css

.question {
text-align: center;
position: relative;
top:400px;
}

I change 40px to 400px just for a proper change

Here is index.html code

as you see there are 2 div’s with class name question

my output is

image 1

Imgur

image 2

Imgur

as you see in Image 1 there is proper 400px gap between top and question 1 but in Image 2 why there is no 400px gap .As i know if i am giving 400px gap from top to class question than every div who have class question should have gap of 400px from top.

now you still apply the top: 400px still to all questions, not only the first one

anyway, as explained earlier (please checkout the jsbin example as well):

So all the questions move down, but because they all move down an equal amount (40px, 400px or whatever value you give them), the relative distance between the questions stays the same.

Thank you very much sir
It cleared my doubts

I added the position - top 40px in the class “question”, There is only changing top of the first question box but why another questions box`s top are not changed? They are also included to class “questions”.

they are, i explained it here:

i even included a simplified jsbin example to play with.

Hi,
Thanks for the responses but still not quite getting this. I played about with your jsbin. This is the start position, before we add relative positioning:
30

(can only add 1 image per post right now so will reply again with next step…)

Part 2:
Then added relative positioning. In this example, I see what I would expect - each relatively positioned element has the additional space above it, relative to the last (static) element:

Really struggling to work out the difference between the lab case and this case.
All clarifications gratefully received!
Thanks

debugging from screenshots is very difficult, couldn’t you post links to the bins?

Hi stetim94,
sorry, first time I’ve ever seen jsbin so not sure what you mean - could you clarify what links you mean.
Thanks

Believe this is what you’re after but let me know if not - Thx

well, in the lab (the codecademy exercise) all questions are positioned relative. which means you have a few relative elements after each other, while in your jsbin example you have relative and static element alternately.

Ah, this is because the answer class element is a sub-element of question class element so we position relative to the previous question as opposed to answer, as I have tried to simulate? (apologies if terminology not correct - early days of learning…)

yes, seems you understand it correctly
