css3 - Is there a SASS/CSS selector for items WITHOUT a particular adjacent sibling? -

-

मैं सभी & lt; li & gt; वर्ग के साथ तत्वों को "foo" जो कि "बार" के साथ एक & lt; li & gt; तत्व के एक आसन्न भाई नहीं हैं

क्या एक "आसन्न भाई बिना [x]" एसएएसएस / सीएसएस चयनकर्ता है? या यह दो नियमों के माध्यम से पूरा करने का एकमात्र तरीका है, सबसे ऊपर सीमा को और लेफ्टिनेंट; li class = "foo" & gt; एस और दूसरे को से दूर ले जाने के लिए जोड़ें ; Li & gt; & lt; li वर्ग = "बार" & gt;

जब मैं कर्कशता से निहित होता है, तो आप यह करना चाहते हैं:

HTML 

  & lt; ul & gt; & Lt; li वर्ग = "बार" & gt; बार & lt; / li & gt; & Lt; li वर्ग = "फू" & gt; foo & lt; / li & gt; & Lt; li वर्ग = "फू" & gt; foo & lt; / li & gt; & Lt; li वर्ग = "फू" & gt; foo & lt; / li & gt; & Lt; li वर्ग = "फू" & gt; foo & lt; / li & gt; & Lt; li वर्ग = "बार" & gt; बार & lt; / li & gt; & Lt; li वर्ग = "फू" & gt; foo & lt; / li & gt; & Lt; li वर्ग = "फू" & gt; foo & lt; / li & gt; & Lt; li वर्ग = "फू" & gt; foo & lt; / li & gt; & Lt; li वर्ग = "फू" & gt; foo & lt; / li & gt; & Lt; / ul & gt;

सीएसएस: 

  li: नहीं (.बार) + li.foo {बॉर्डर-शीर्ष: 1px ठोस नीला; }

प्रत्येक और lt; li class = "foo" & gt; को चुनने वाला चयनकर्ता यह & lt; li class = के एक आसन्न भाई नहीं है; बार "& gt;

इस चयनकर्ता में केवल एक प्रमुख & lt; li & gt; की आवश्यकता की कमजोरी है। यदि पहला आइटम और lt; li class = "bar" & gt; नहीं है, तो आइटम छोड़ दिया जाएगा इसे यहां पर देखा जा सकता है: 

  li: नहीं (.bar) + li.foo, li.foo:first-child {सीमा-शीर्ष: 1px ठोस नीला; }

पी.एस. जब आप एक सूची के अंदर आइटम समूह करना चाहते हैं तो आप परिभाषा सूचियों & lt; dl & gt; या नेस्टेड सूचियों का भी उपयोग कर सकते हैं। इससे इस तरह की समस्याओं को रोका जा सकता है।

uislider - In a MATLAB GUI, how does one implement a continuously varying slider from a GUIDE created .m file? -

-
I am trying to create a GUI with a plot and a slider. The slider should be described as continuously and output. I have a problem with this explanation that the uicontrol object is programmatically created, on the contrary, I want to know that in the last three instances, to complete the same thing done according to the program What can be added to a GUI file that is created. The code is down, and I have marked the (wrong) code that is provided by some of the above examples. Thanks a lot for any help! This slider function sets P1_slider_Callback (hObject, eventdata, handle) (handle, dragon, 'string', num2str (get (hObject, 'value'), 3)) PlottheData_Callback ( HOBject, EventData, Handle)% "PlotHeadata" is a button that creates the data slider based on the value of P1_slider%, and I think that here "p1_slider_CreateFcn" (hObject, eventdata, handle) needs to be assembled (HOBJECT, 'BackgroundRoller'), (0, 'Default UITTACKBACK MANDROLLE...

python - Django Custom Admin Block For center of admin -

-
So I'm overriding change_form.html to add some features to my admin page. Everything is working fine, I am currently using the "after_field_sets" block, but I want to put content between this field in my field_sets, not after that. I set the field above and below the new set, but I can not understand which block is used to put them in the middle of field sets. There is a list of all blocks text "> After reading the code referenced by the link you posted I reached the conclusion that the block you are looking for does not exist in it called content There is a block but more than just that "main content" but this is not the end of the world, you still have to make the template IR order to "make some space" for your content. Remember Padit can. And very important, keep in mind that you can css and js edit files as well.
