I need two divs to look a bit like this: | | ---| LOGO |------------------------ | |_______________| LINKS | | CONTENT | What's the neatest/most elegant way of making them overlap neatly? The logo will have a fixed height and width and will be touching the top edge of the page. Owen I might approach it like so (CSS and HTML): html, body { margin: 0px; } #logo { position: absolute; // Reposition logo from the natural layout left: 75px; top: 0px; width: 300px; height: 200px; z-index: 2; } #content { margin-top: 100px; // Provide buffer for logo } #links { height: 75px; margin-left: 400px; //

Getting results between two dates in PostgreSQL

问题 I have the following table: +-----------+-----------+------------+----------+ | id | user_id | start_date | end_date | | (integer) | (integer) | (date) | (date) | +-----------+-----------+------------+----------+ Fields start_date and end_date are holding date values like YYYY-MM-DD . An entry from this table can look like this: (1, 120, 2012-04-09, 2012-04-13) . I have to write a query that can fetch all the results matching a certain period. The problem is that if I want to fetch results

Meaning of overlapping when using memcpy

问题 I am trying to understand the function memcpy() which is defined in the C library <string.h> Syntax: void *memcpy(void*dst,const void*src,size_t n); I know that this function is used to copy the contents of the memory pointed by pointer src to the location pointed by the dst pointer and return a address pointed by dst pointer. I am not able to understand the following important statement regarding memcpy() : When using memcpy() , memory address should not overlap, if it overlaps then the

问题 I require your help, I have a problem (see picture), I have let say two arrays and each of this array contains intervals with different length and real values and I need to find out how I'm gone overlap this intervals efficiently. I'm open to ideas, or paper theory or concret algorithms which will let me find a way out! I'm guessing about to transform this somehow in waves and overlap them. Its very important, its for my thesis. as an example, here in numbers to explain it better: Array: 1-2,

Checking a table for time overlap?

旧城冷巷雨未停 提交于 2019-11-26 18:54:00
I have a MySQL table with the following fields: name starttime endtime starttime and endtime are MySQL TIME fields (not DATETIME ). I need a way to periodically "scan" the table to see if there are any overlaps in time ranges within the table. If there is an event from 10:00-11:00 and another from 10:30-11:30 , I want to be alerted of the presence of the time overlap. Nothing fancy really, all I want to know whether an overlap exists or not. I'm going to be using PHP to execute this. This is a query pattern for which I found the answer many years ago: SELECT * FROM mytable a JOIN mytable b on

Collapse rows with overlapping ranges

问题 I have a data.frame with start and end time: ranges<- data.frame(start = c(65.72000,65.72187, 65.94312,73.75625,89.61625),stop = c(79.72187,79.72375,79.94312,87.75625,104.94062)) > ranges start stop 1 65.72000 79.72187 2 65.72187 79.72375 3 65.94312 79.94312 4 73.75625 87.75625 5 89.61625 104.94062 In this example, the ranges in row 2 and 3 are entirely within the range between 'start' on row 1 and stop on row 4. Thus, the overlapping ranges 1-4 should be collapsed to one range: > ranges

Is this correct? SELECT * FROM contract JOIN team USING (name_team) JOIN player USING(name_player) WHERE name_team = ? AND DATE_PART('YEAR',date_join)>= ? AND DATE_PART('YEAR',date_leave)<= ? My table contract has the player name, team name and the dates when he joined and left the club. I want to make a function listing all players that were on the team in specific years. The above query doesn't seem to be working ... Scott Marlowe Why not use between without the date part thing: WHERE datefield BETWEEN '2009-10-10 00:00:00' AND '2009-10-11 00:00:00' or something like that? The currently

Here is the situation: body { margin: 0; background: pink; color: #fff; } .box { margin-top: 20px; background: red; } .bottom { text-align: right; background: green; animation: animate 2s infinite alternate linear; } @keyframes animate { from { margin-top: 10px; } to { margin-top: -40px; } } <div class="box"> some content </div> <div class="bottom"> other content </div> What's happening? As you may see we have two div without any complex styling (simply background-color). I am making the second div to overlap the first one by applying a negative margin-top . I am expecting to see one

Is it a bad practice to use negative margins in Android?

Demo of negative margin: The scenario Overlapping views by setting a negative margin to one of them so that it invades the bounding box of another view. Thoughts It seems to work the way you'd expect with overlapping of the layouts if they should. But I don't want to run into a bigger problem for unknowingly not doing things right. Emulators, physical devices, you name it, when you use negative margins everything seems to work correctly, one view invades another's views bounding box and depending on how it's declared in the layout it will be above or below the other view. I'm also aware that
