      Guidelines and Netiquette   03/28/2017

      Posting Problems:   Having problems posting your topic? Read through this: To join, you agree to our terms and conditions and fill out and submit a registration form. An activation email will be sent to your email adress, so you'll need to verify your account. After that the account has to be validated by one of the moderators. This will mean that it can take up to a day to be activated. A couple of things to remember to ensure approval: Don't use an email address in one of those $2 four character .com domains eg. xyds.com. These will be deleted and the domain added to the banned list. Don't use an email address that is within a domain with a bad reputation for spam. A Google search is run on every email address and email domain. Don't sign up with an email address that doesn't exist, doesn't work or requires the sender to answer a quiz before their email can get to you. Put your country and or state and city in the signup form. Blank forms will go to the botton of the "to do" list. And make sure that your email address and your country match, saying you're from Alabama and using a .ru email address is not going to get you activated. After a membership is activated the first few posts will be monitored. Posting spam or unapproved topics described in the agreement results in an immediate ban. The email provider and the IP addresses associated with the account will be banned and all posts will be deleted. These strict measures have been deemed necessary to hinder spam. Sorry for any inconvenience this causes, but it's not liable to change. If, after reading this, you still can't post and don't understand why, contact one of the Moderators listed here.   Topic Guidelines   Including the following information can expedite an accurate response from board members: Must be a Specific Problem or Question related to web design and development Include Code in Question (wrap with   for small blocks of code and for longer blocks   ) Include Code Author Include Extra Notes/Modifications/Attempts Include web link to page/file when possible Content Guidelines   You may not post, upload, link to, or email any Content that contains, promotes, gives instruction about, or provides prohibited Content.

There's no need for calling someone stupid if they ask an 'easy' question. Keep your avatars and signatures absolutely child friendly. We have a younger audience on this forum. Keep your language appropriate for the same reason above. Do not PM moderators for help on the forum. Post on the topic, or create a new one.   Spam:   Recently, as you have all without doubt noticed, we have had lots of spam and advertisement on the forum. Therefore, we'd like to alert you as to what to do when you have found any of the aforementioned annoying messages: it. Immediately. Give a clear reason, please, if the advertising is not evident. DO NOT POST! Report, let the post stay as is, and we will get to it, meanwhile if you continue to post as normal in the other threads, it won't be on the top so long. Refrain from PMing the member. This won't help at all, as they are most likely spambots anyway. Thank you.       Images in signatures:   After thinking of users on dial-up, we have decided to enforce the following rules regarding signatures. Please pay heed to them. Respecting these rules is respecting the members on this forum with dial-up. Signature rules: No animated images AT ALL. No matter the amount of animation. Maximum image widthxheight: 300x150 Maximum image (file) size: 15kb Use calm colors. Do not use highly contrasting images in your signature, as this can get really annoying when seeing several posts from one member in the same thread. The same prohibited content goes for images as for posts. Lastly, use common sense. No lengthy signatures please. Save us some scrolling. Thank you.       Links in signatures:   Please understand that w3schools.com only exists because of voluntary work and is barely supported by the advertising littered throughout the tutorials and the forum. So, please, stop advertising other sites. DO not post links that drive traffic away from the w3schools domain - especially to a site that offers similar if not identical information. Please help support the site by keeping individuals on it. Thank you. Here are some guidelines as to what you can put in your signature: w3schools links --> allowed w3.org links --> allowed browser links --> allowed html editor links --> allowed personal sites --> allowed tutorial sites competing with w3schools --> NOT allowed sites completely irrelevant to webprogramming and this forum --> NOT allowed   Thanks for understanding, and for taking the time to read this. ~W3Schools Modstaff~

Z-Index issues with modal and dropdown menu

Recommended Posts


I am new here and was wondering if I could possibly get some help.

I am having some serious trouble trying to figure out why my menu won't sit behind my modal. =(

I have wracked my brain trying to figure out what it could be, but have not been able to come up with a conclusion.

Please ignore the text as the page is obviously still in testing, but the page shows how the modal goes in front.

I also have other issues with IE in that the menu doesn't show up properly, but that may be due to too many style tags? I do very much enjoy my CSS. lol

Things have evolved since 2009 ^_^;

Here is the link to the page in question and I am attaching the raw files that I think you would need to see where I may have done something wrong. Is it possible that they just aren't compatible?


Thanks in advance! =D


Also... If you could... Could you explain things as simply as possible? I am not as advanced with coding in knowing all the terminology such as parent and sibling elements. >_<!

You have to give navbar position: relative; and z-index lower than the modal background, BUT! you have a bigger problem in that you are using position: absolute; for layout purposes, which is a big NO-NO, will cause you more problems in allowing responsive html to flow and adjust to different devices.

Also body html elements is not allowed in between <head>...</head> use link element instead to link to external css.

Use float: margin: padding: display: for layout purposes and only use positioning for pop-ups and overlapping purposes as use for modal.

validate html at https://validator.w3.org/

Thanks for the advice, but... I still can't get it to work. I have tried a buncha different combos and failed again. =(

Is it possible to give me an example in how it will work? I am about to just give up, but really want to make this work, because it fits the vision i had for the layout. =(

Any elements with z-index is relative to sibling element of the same level, and child elements of that element are only relative to child sibling elements of that level within that parent. A higher child z-index won't place it at a higher level than any parent sibling elements z-indexes, only the parent can do that.

So a parent container is always the uppermost level to whatever its child element level is, this continues on with children elements of the child elements which is there parent and so on.

NOTE: However early versions of Firefox, and maybe present version does not follow this rule completely, but you should follow this rule set up above.

You have your modal position fixed using z-index: 999 within a parent element using z-index: 2; your navbar parent is using z-index: 3; like already mentioned the parent of z-index: 999, will be the highest above any children set levels, so navbar parent z-index: 3;  is higher than modal parent z-index:2, so it will overlap the modal.

Thanks again! I think I am beginning to understand things a little more. I just want to make sure I understand parent-child elements. So the parent would be the CSS style sheet. Like the element defined in there. Then, the child would be what is in the body of the html file. So what I set in the css takes priority over everything else... Right?

So... Essentially I need to focus on getting everything organized within the parent-child situation...

I should sniff through some css tutorials some time. I feel like that would benefit me greatly...

I'll report back once I do some editing!

Thanks once again for the help! You're awesome! =)




I think things are making a lot more sense now. the z-index is a lot more complicated than i originally thought. I thought you had to use it for everything, but you don't. Nifty =)

Thanks again!!!! =D!!!!!!!

A element with id reference can only have a unique singular value within a page, you will find that only one of these  multiple id reference elements with identical id is being used at a time, the rest will be ignored, and clutter up your page with unused html.

"Parent" and "child" refer to the relationships between HTML elements. The CSS stylesheet is not the parent of anything.

In the following code, <div> is a parent of <span> and of <a>. <span> and <a> are children of <div> and are siblings of each other:
