Bootstrap grids dont go next to each ther12/31/2023 ![]() The three sections to be the same height with the images on top andīutton on the bottom. On wider screens we want the navigation to appear on top, and we want In just a few lines of CSS, we can make this layoutĬompletely responsive: html Its developed using flexbox and is fully responsive. We lay the site out for smaller devices, then alter the appearance for Ways to work with the Bootstrap grid: Bootstrap Grid System works with a set of rows, columns, and containers to layout plus align material. Here is the aside Home About Blog Careers Contact Us Copyright © 2017 My Site In this scenario we will have the navigation appear between the header and main content on wide screens, with the navigation below the content in both the markup and on narrow screens (see Figure 4-1): Document Heading This is the heading of the main section This is a paragraph of text. It’s built with flexbox and is fully responsive. It makes me wonder how many other things get overridden because of Bootstrap - especially really complex things like the FNC Page Control.We covered a typical layout in Chapter 3. How it works Bootstrap’s grid system uses a series of containers, rows, and columns to layout and align content. it has taken a while to get used to the fact that if you copy and paste certain things (eg., TWebLabels) where the ElementFont is set to efProperty gets changed back to efCSS when it's pasted, so it doesn't work without changing it back right away. The problem is, some are really hard to tell if they're from MY code or the fact that this whole facade is running on top of HTML, CSS, and javascript. I just seem to be running into a lot of them. I don't expect it to be free of quirks and glitches, as long as I can find workarounds for dead-ends I encounter. (I could have made them all the same color, but I guess I was excited to finally find something that would show a color at run-time other than clBtnFace.)ĭon't get me wrong. But it took three different approaches to get something that I could have done fairly quickly in VCL. I settled on something like a trackbar that has 7 segments, each one a different color (think rainbow) and they light up to reflect the internal state. I guess the Good News is that this little display was an outgrowth of the issue originally mentioned here because I had no way of seeing what the internal state of my app was, so I made something to display it. ![]() Then I tried an FNC Panel and viola! The colors show up! I tried to use a string grid, but got three different compiler errors that blocked me from going further. ![]() Bruno has shown it work in isolation, but I can't get it to work in my form. But some are behaviors that just don't work as expected.įor example, I have not been able to get TWebPanels to display a color on them, no matter if I set it at design time or at run-time. In many cases it's because of undefined properties or methods or other things that raise compiler errors. I've spent an unexpectedly large amount of time having to find workarounds for things that don't do what they should. The behaviors of VCL components is very consistent and predictable. This may be related, but I can't say for sure. Having Bootstrap active, I notice some unexpected things from time to time. It has come up previously which is why I decided to mention it, but in this case there seems to have been an explanation. Has anybody else run into this and solved it? If so, what did you do? But I need it to work like VCL Page Controls where the contents of a tabsheet don't completely reset if you click on another tab and then come back.Īlso, I have some nested page controls so it's not always switching from one tab to another in the same control it can happen when you go to a sub-tab, then switch tabs to another one in the parent and then go back. I don't know if this is a "bug" where the Z-order inside of the Page Contols is not being managed correctly, or just another side-effect of dealing with an inherintly stateless canvas. In this case I'm using an FNC Page Control, but it happens with the regular TWebPageControl as well. Resetting the visual display like this totally screws-up all of the "work-in-progress" that has already happened. This poses a problem in my case because I'm creating and allocating things to some lists and using content in the controls to know where the user is at in their process, like checklistboxes, grids, multi-selections, treeviews, things in memos, etc. ![]() At least, not in my app when I select a different tab in a Page Control and then return - the visual controls on the previous page lose any changes that may have been made. I've noticed that forms in WEB Core are not stateful. ![]()
