Hello everyone, my name is Sebastian. I’ve designed Microthemer for developers as well as beginners. My aim is to level up beginners by exposing the CSS code Microthemer generates when using the visual controls. This is of course helpful for developers who may wish to make manual edits. Some developers use Microthemer as an in-browser CSS or Sass editor, and just lean on the interface for element selection or more advanced properties like filters, grid, and animation.
I’ve been happily developing Microthemer and supporting users of varying technical experience in my forum for many years now. I’m always ready to answer questions about the software and help out with CSS hurdles. Please don’t hesitate to get in touch!
- Click the ‘Plugins’ menu option in WordPress.
- Search for ‘Microthemer’.
- Install and activate the plugin.
- Go to the ‘Microthemer’ menu option.
- Start customizing the appearance of your site.

- ::before and ::after pseudo elements shown in the HTML inspector.
- ::before and ::after pseudo elements can be visually clicked to select them.
- ::before and ::after pseudo elements can be created using the selector variations option.
- The selector modifier checkboxes synchronise with the selector code as it is edited live.
- An issue using the dropdown menus on empty fields when the computed value was [mix] (meaning different for multiple elements).
- The options above the selector variation options did not update properly when switching between variations.
- Element border highlighting displayed outside the main container.
- The cancel selector targeting icon could be cut off sometimes.
- The settings panel could have horizontal scroll if the history menu was expanded and contained long names.
- An issue triggering Bricks form submissions even when Microthemer’s targeting mode was disabled.
126.96.36.199 (May 26th, 2022)
- An import CSS issue caused by the previous update.
188.8.131.52 (May 25th, 2022)
- An error occurred when enabling Sass support on a fresh install, or if no code had been added to the full code editor.
184.108.40.206 (May 11th, 2022)
- Some missing icons in the CSS reference.
- Possible PHP notice on site frontend with WP_DEBUG active: Notice: WP_Scripts::localize was called incorrectly.
- The MT logo displayed very large when loading MT with dark mode and the style options docked top.
- The selector suggestions popup could not be triggered on top aligned elements if the WP toolbar was not showing.
- The selector suggestions popup did not display in the detached preview window.
- The “Oxygen Elements for WooCommerce” plugin caused Microthemer’s frontend script to load multiple times, which caused odd behaviour.
- On-canvas padding highlight could be offset.
220.127.116.11 (April 25th, 2022)
- Added a better fallback option if ZipArchive PHP extension is not installed.
18.104.22.168 (April 23rd, 2022)
- Possible PHP error if ZipArchive extension was not installed.
22.214.171.124 (April 20th, 2022)
- JS error that could arise on loading MT: Uncaught TypeError: labelCodeStr.split is not a function.
126.96.36.199 (April 20th, 2022)
- MT wraps URL paths with url(“”) in input field (not just in the editor) for consistency with mask-image.
- Slider generated NaN on properties that don’t have a unit (e.g. opacity).
- The new clip-path and shape-margin properties were not listed in the transition property menu.
- Microthemer was not reloading the CSS property reference when launching from a different property.
- No dashed outline was shown when hovering over the currently selected element when element highlighting was switched off.
- MT did not auto-wrap plain file paths with url() for background-image or mask-image if URL parameters were used.
188.8.131.52 (April 14th, 2022)
- The “M” toolbars preset set the left columns to full height by default.
- Added support for CSS mask, clip-path, and shape-outside properties with stock SVG mask images and clip-path shapes.
- Added object-fit and object-position to the Dimensions property group
- Added a quick navigation toolbar for the property groups when the styles are docked left. This can be turned on or off via Settings > View > Fine tune layout > Sticky styles toolbar.
- Microthemer’s slider, mousewheel, and keyboard number adjustments can be applied to single numbers when there are multiple numbers in a field. This is useful for adjusting e.g. background-position, polygon, and gradient position/opacity values when used as an image-mask.
- Resizing the side panels caused the current property group to reload, which reset the scroll position and removed grid rows/column that hadn’t been given a value yet.
- The HTML pane could become out of sync with the DOM elements if a script tag contained a string with a closing style tag. This affected Oxygen 4.0.
- Microthemer could sometimes scroll to the top of elements even when they were already in view.
- Typing styles in the full code editor could (re)trigger scrolling to the currently targeted element. This was only meant to happen when the cursor is positioned inside a new selector.
- The mt-inactive.zip file for loading MT CSS with a simple plugin was missing.
- Searching the CSS property menu suggestions could result in a spinning gif and an error message.
- A conflict with Astra caused MT to always select the mobile navigation close toggle (#menu-toggle-close).
- Firefox had a delay in style rendering when using the CSS property slider.
- Some layout issues when using Microthemer on a very small screen (approx 500px).
- Setting a new folder name when creating a selector generated an error.
- MT did not sync comma separated CSS property values in the editor with the UI, at times when it should.
184.108.40.206 (March 10th, 2022)
- Added an option to preferences for disabling targeting mode by default when Microthemer first loads. This may be useful for devs that prefer to code selectors manually, without assistance from Microthemer.
- Text in the Google search field was the same color as the white background when the light theme is active.
- Entering align-items in the code editor synced with the flexbox UI fields, rather than the grid fields, even if the display property was set to grid.
- Setting a CSS Modifier like :hover or :first-child did not update the full list of selector suggestions in the top toolbar.
- Setting a CSS Modifier removed the “>” character from selectors.
- Removed some unhelpful selectors from the suggestions lists e.g. div:nth-of-type(1).
- When exiting a page builder with deep integration (Beaver Builder, Elementor, Oxygen), Microthemer was enabling targeting mode, even if it wasn’t on before activating the builder.
220.127.116.11 (February 16th, 2022)
- The code editor did not recognise the following pseudo selectors as valid :has, :is, :where

- An error could happen when selecting elements at the point of maxing out the number of selectors allowed in a folder.
22.214.171.124 (January 25th, 2022)
- An error that could occur when selecting multiple text inputs using the shift key could generate a downstream JS error when loading Microthemer: unauthorized TypeError:i.split is not a function.
126.96.36.199 (January 21st, 2022)
- PHP Warning: Illegal string offset ‘label’ in tvr-microthemer.php on line 5589.
188.8.131.52 (January 18th, 2022)
- Improved compatibility with Bricks builder – Microthemer now has a workaround for creating CSS grid layouts on container elements that also display in the Bricks editor. This workaround is on by default, but can be turned off via the preferences. There is also an option to remove the workaround from all selectors automatically, as it may become redundant in future.
- When clearing the top field for editing selector targeting, and then typing very quickly, an error could be generated: “this.source is not a function”.
- An upgrade error could happen if old MT settings contained data that hadn’t been cleaned by a more recent version of Microthemer.
184.108.40.206 (January 16th, 2022)
- Styles applied to Bricks container elements also render in the Bricks editor which makes it easier to apply CSS grid layouts to Bricks content using Microthemer.
- The grid controls could display behind the options panel with certain toolbar layout configurations.
- Artificial Microthemer body and HTML classes were being included in the selector suggestions list.
220.127.116.11 (January 14th, 2022)
- The detached preview layout did not load properly due to a JS error “TvrLang is not defined”.
- Microthemer’s targeting did not resume when switching between pages on the frontend.

22.214.171.124 (January 12th, 2022)
- An issue with the dropdown menus on the standalone preferences page.
126.96.36.199 (January 12th, 2022)
- Using the re-target selector option could sometimes save the preliminary retargeting even if it was cancelled.
- The color picker could generate an error after re-targeting a selector if it was opened just before re-targeting.
188.8.131.52 (January 8th, 2022)
- The opacity input field was not working properly.
184.108.40.206 (January 7th, 2022)
- Minor performance increase.
- Some terminology updates to make it clearer that styles are saved as a draft until the Publish button is clicked (unless auto-publish is enabled).
- When adding a new selector to a closed folder, not all selectors in the folder displayed alongside the newly added selector.
- Sometimes entries in the history table could say simply “false”.
220.127.116.11 (January 7th, 2022)
- The previous update caused an issue loading the MT interface on some sites, due to an issue with the JS script loading order.
18.104.22.168 (January 6th, 2022)
- Added auto-publish option to Settings > General.
- Added support for completing a firewall captcha form when submitting a license key from a server with a blocked IP address.

- Styling issue with CSS reference – white BG and spinner could display below scroll area.
188.8.131.52 (December 27th, 2021)
- An issue loading tooltips on the frontend could cause issues loading MT.
184.108.40.206 (December 22nd, 2021)
- An issue with the color picker closing when using the VAR field and generating an error sometimes.
- Color picker opacity slider could overlap the VAR dropdown menu.
- Dark theme colors could display in odd places (e.g. dividers, color picker, input borders) with the light theme if a CSS concatenation plugin changed the name of MT’s internal CSS file that loads on the frontend.
- The top selector suggestions menu could not be clicked under certain circumstances.
220.127.116.11 (December 16th, 2021)
- The previous update could cause the page navigator search to return no results on some sites.
18.104.22.168 (December 16th, 2021)
- When enabling a page builder, Microthemer removes any draft selector, rather than saving it.
- The page navigator was displaying a cached set of pages instead of fetching new results under some circumstances.
22.214.171.124 (December 15th, 2021)
- Context menus did not reposition when the screen cut off some of the content.
- Sometimes “undefined” could appear in the editor, rather than an empty string, if no property value was set.
- Scrollbars could appear on the single selector editor when docked top.
- Draft selectors were not removed when using the folders pane to navigate to an existing selector.
- Copying a draft selector did not save it properly.
- A warning could popup saying “Selector name already exists” when clicking on a draft selector that wasn’t properly saved due to the previous two issues.
- Matching search text in the page navigator was the wrong color (poor contrast).
126.96.36.199 (December 14th, 2021)
- Brand new selectors did not save when using the single selector editor on a responsive tab and typing some CSS to confirm that the draft selector should be kept. This only happened when typing speed was neither very fast nor very slow, due to the way the auto-save system works.
188.8.131.52 (December 9th, 2021)
- The color of CSS or Sass comments when using the code editor with the dark theme.
- The grid highlighting persisted when collapsing the MT interface
- If the grid canvas was expanded, it continued to display when going back to the properties list when styles were docked left.
- The Google font field was a bit small with the styles docked top.
- When playing around with the layout options, sometimes overflowing docked top styles could overlap docked-left/right panels, instead of being hidden.
- Folder search could generate an “invalid regex” error under some circumstances.
- When doing a folder search, clicking any matching CSS code did not always work.
184.108.40.206 (December 6th, 2021)
- Due to the fix in the previous update, the loading spinner could remain in place if the site preview page had very little content.
- A light gradient was used to fade out overflowing responsive tabs, even with the dark theme.
220.127.116.11 (December 2nd, 2021)
- On some servers, a forbidden error message was shown instead of Microthemer’s site loading spinner.
18.104.22.168 (December 2nd, 2021)
- With the dark theme, the scrollbars are easier to see.
- Values in the history table have been emboldened to make them easier to read.
- Under some circumstances, the icon font didn’t load properly.
- An error in the sample code for loading Microthemer CSS manually.
- Switching the low/high specificity toggle did not update the selector label.
- Context menus, that are draggable via the header, did not have the correct cursor move icon.
22.214.171.124 (November 25th, 2021)
- When you select an element, and an existing selector targets it but in a different view (full code editor vs GUI), Microthemer notifies you about this rather than automatically switching view. This was a problem when universal selectors were used (*). And there may be other edge cases I haven’t considered.
- When using a universal selector (*), every element had blue highlighting to show you’ve created a selector for it. And while technically true, it obscured a useful feature.

- The settings toggle at the top right is hidden when the settings are permanently docked in view.
- Oxygen device switching options did not work when loaded inside Microthemer.
- The manage packs page did not update after a fresh export of settings.
- The edit design pack icon prompted an ‘Are you sure you want to delete this message’.
- The text editor did not always fill the available height when docked left.
- The checkboxes could be cropped on the ‘Export’ page on some screens.
- Microthemer beatified the minified CSS file when display it, so it wasn’t clear if minification was working.
- Display issue when folder and editor were docked left, but styles were docked top.
- Issue with dragging Grid template areas, the controls could get stuck. And dragging anywhere outside the grid canvas removed the area (not just when dropping on the clear item).
- The CSS grid controls could get stuck when dragging the last item outside the graph area.
- Toggling the folders off didn’t always bring content hidden underneath back to the top.
- In the full code view, switching the editor from docked top to docked left set it’s width to zero.
- Microthemer was not remembering the cursor position for the single selector editor when switching responsive tab or between selectors.
- Disabling Beaver Builder via Microthemer’s switch did not work of no changes had been made in BB.
- Scrollbars for Google fonts browser and frontend and were not dark even if dark mode was enabled.
184.108.40.206 [beta] (November 17th, 2021)

- Loading Oxygen via the Integrations menu had a false positive warning “Page not editable with Oxygen”.

- When leaving an unsaved Oxygen page, Microthemer did not release the Oxygen post lock when exiting via the Integrations menu switch. This causes issues for re-enabling Oxygen (an MT interface refresh was needed).
126.96.36.199 [beta] (November 2nd, 2021)
- The loading order of Microthemer’s stylesheet can be customised via the preferences.
- The prefix used for page specific body classes can now be customised. And the default value (for new installs only) is ‘mtp’ rather than ‘mt’. This change is due to a conflict with tailwind and boostrap with use e.g. .mt-4 to set margin-top, which could result in unwanted top margin on the body element.
- Enabling Sass resulted in an error.
- ‘Fold widget’ error when Microthemer was loading if cursor position was left at the end of the editor.
